The Hugger goes ZL-1....
« on: August 19, 2015, 09:51:09 AM »
Hi guys,
During the 10 years that I now have had my Camaro it has gone thru a lot of different shapes, not much has changed every time but something.
I've also tried to walk on the thin line between what was original to the car and adding some mild customizations...I want the car to behave well and still look as it could have done in the 60_ or 70:ies!  8)
Here is a kind of resume and examples of what I´ve done with the car so far.

This is how it locked in the ad at eBay 10 years ago, taken from its origin in Waterloo, Illinois:




It was a descent restoration but much were loose due to a fast selling procedure. The wheels had wrong backspace and were made for a Corvette, therefore it was equipped with hi-jackers! First thing was to get rid of the ugly jackers, swap the wheels to 18" American Eagle and a lot of small corrections...


After that I mounted a Hotchkis sport leaf kit and adjusted the exhaust:


...the engine bay before and after minor adjustments:




I got tired of the bling-bling and the wheels set up went to original look:


Changed the grill color for correct argent silver:


Done some touch up for the interior as well....before:


...and after:


Then it was time for the larger bumper guards. I think this has been on the car as an option from the beginning...it seemed that way in the front at least. I also widened the rear rims so they now are 14x7" and the front is 14x6. Were lucky to find some NOS rear tires with the dimension H70-14!


The latest, so far, set of wheels are these almost period correct American Racing S200, though these are 17" and with custom built backspace for The Hugger. Its great to have another set of wheels to alternate with for the steel wheels, which I always will keep!

The next level in my life with a 69 Camaro - the engine swap!
I've always loved the real deal COPO 9560 and it has certainly had an affect on me how I've putted the car together so far...I certainly don't have the money to buy a genuine 9560 so the second best for me is to build my own ZL-1 engine and put in The Hugger!

This project doesn't have a specific deadline so I'm going to update this thread whenever something new has happened and when I've the time, and money, necessary to continue the swap.

The background data on the car is rather interesting because The Hugger is a original X44 car and also the VIN is close to the VIN that the 69 original COPO 9560 had......so who knows?  :P
It already has a 12 bolt Chevy rear with 4.10 gear, front disc brakes and the steel wheels with dog dish caps.
We will also try to keep the TH350, the cooler, front springs etc to keep the cost down but still get a functional car!?

Just to clarify, were not going to build a perfect COPO clone here but as close as we can with the given conditions! Fell free to comment and help us during these project, I know you guys have tons of information of how this should be made as good as possible and I'm all ears!  :)

....this will be continued. Welcome!
Regards,
Hakan from Sweden

You have a great looking car, Hakan!  .. and I like the changes (improvements) you've made to the car over the years!  Personally, I like the car the way you have it now, but if one has to 'have a big block', then an all aluminum ZL-1 is a great way to go!  :)

Hakan,
Looking real good there! How did you widen the rear steel wheels to 14x7?  And....Hugger Orange does rule, especially with a big block! Way to go.  8)

Didn't the COPO cars come from the factory with 14x7 steel wheels and little caps?  :)

The standard wheel for COPO 9560 & 9561 was the same 14" x 7" wheel [XT code] used on Camaro SS. Some were ordered with rally wheels; those were also 14" x 7" [YJ code] optional on Camaro SS.

COPOs also ordered with COPO 9737 Sports Car Conversion received 15" x 7" rally wheels [YH code] with E70 x 15 tires as used on Z/28s. COPO 9737 was only available with COPO 9560 or 9561.

Thanx Gary, really like your support! :)
Since the the original V8, whatever it was, is long gone I thought it would be fun to get the ZL-1!

Hey I like the changes you have made thus far. (I am on the fence with the front bumper guards)
So my question is how far are you going to take it?

Are you going to pop off the 350 emblems &  fill the holes ?
Remove the white stripes?

I know the current mechanical gauges you have are probably very accurate, but are you going to put the factory gauges in ?

What is your image of the car being done?

Thanx, man!
I took the wheels to a shop that's specialized in widening rims and we made them 1" on the outside to get more depth for the hub cap! :)
Its very professional done and looks like an original rim.
Hugger orange always rules and its original to this car..... 8)

Hey Bullit,
I just love the bumper guards, makes the car looks meaner in my opinion, but this are things that are so easy to change so...and, as I wrote earlier, I think they have been in the front all the time cause the holes seems were already there when I bought the car and the look old...!?

Regarding how far I will go it depends of money and time! :)
I want to repaint the car in the future and that includes to get rid of the stripes, remove the holes in the fender, drop the spoilers and maybe put factory gauges in the console!
I also want to put the DX-1 stripe on it but I want the complete stripe kit made of vinyl, anybody seen that? I can't find anything but the painting stencils and that's not what I want....:(

During the time I've bought the incorrect 427 fender emblems, but they fit in the same hole as the 350:ies.... :)

If you're going to build this kind of high end engine you have to start from the ground and what's more suitable then the block? ;)

As you guys already know the real deal ZL-1 block from 1969 to the 70:ies cost a lot of big money so that's out of the question, for me at least....  ::)
Then we heard that Chevrolet Racing Parts, you can read more here  http://www.superchevy.com/features/sucp-0109-chevy-zl-1-engine-new/, had started to make new ZL-1 blocks from the old original tooling! Now things starting to get interesting........

We did a scan of eBay and after a while we found a brand new 12370850, which is new part number from Chevrolet, to the right price and took it home to Sweden:






There is a serial number with the new block but I'm not sure how to value that? Does anybody know how many of this new casting Chevrolet have made so far?


Great detailing:


Far as we know these new castings have the same casting number as the original 1969 blocks from Winters Foundry, #3946053!
We haven't had the block out of the wooden box yet to confirm this.....we are waiting for the rest of engine parts before anything happens....

This is how Chevrolet describes the block themselves:

The Chevrolet ZL1 Aluminum Big Block is back and better than ever. This block was first introduced in the 1969 Corvette and Camaro. It was one of the rarest production engines ever built. Now the improved version is available. This block is based on the original tooling. The new casting is made from 356-T6M aluminum alloy and has a 4.118" cast iron liner that can be bored to 4.300". The bottom end has also been improved with new four-bolt splayed steel main caps, with dowel pins to locate and hold the caps in place. This block includes screw-in freeze plugs with o-ring seals, and a two-piece rear seal. The new block has a provision for both dry sump or regular oil pump systems and mechanical fuel pump. All GM performance cylinder heads will fit this block and it only weighs 110 lbs. The maximum stroke is 4.375".


....so now it's just to find the rest of the missing parts!  ;D

It really is, thanx!
I bought it from a privat person at the same price and free freight! .....to California will say!
We have a company here in my hometown that get containers from California Shipping almost each month so I got the block to my town Umea, Sweden for like $ 260 incl. shipping, tax and toll!

Well, now we have a block but it takes a couple of things more to get a motor running...a whole lot of things actually :rolleyes:

The carb, Holley 750 CFM, and the cowl air cleaner will be moved from the current 355, they not that bad for the ZL-1 either I guess...?

..but a new intake manifold for BB has to added to the new-parts-list! The original intake for the ZL-1 is the #3933198 as we understand and they are not hard to find but rather expensive so we had something else in mind when we started do discuss the motor...

After a while we found exactly what we were lookin for, the Edelbrock C427X. As we understand it was one of the best hi performance intakes during the 60-70:ies and were commonly used by a couple of racing team including Baldwin Motion?! A hot rod version of a ZL-1 isn't bad either and if we got the that intake to a good price...hey!  8)

After searching Ebay for a couple of weeks we suddenly found that nice unrestored and untouched piece that we wanted and for a neat price of $ 110!




The intake is NOT, I repeat NOT, going to be sand blasted and painted silver, just cleaned in a proper alu-friendly way and then we have to see if it need more TLC!  :-*
We want to keep that old school look in the engine bay....

Connecting rods is a must and this is what we found at eBay:


These rods are one the best that GM made and was made for high performance engines such as the L88, ZL1 and LS7. They are full floating dot rods, 7/16 bolt, magnafluxed and shot peened.

Here´s a close-up of the small end where you can see the full floating. The characteristic "dot" is also seen here and this is why they were called "dot rods"!


I also got some info on the net regarding these rods:
Chevy highperformance “dot” rod with 7/16-inch rod bolts is still a good choice for engines up to about 700 hp. There were three versions of these rods: one with 3/8-inch rod bolts and pressed pins (1965– 1969), one with 7/16- inch rod bolts and pressed pins (LS-6 and LS-7), and a version with 7/16-inch boron rod bolts and full-floating pins, which was used in Chevy’s killer big-blocks, like the L88 and ZL-1.
 
...it also a rumor that's says that Smokey Yunick is the brain behind the "dot rods", true or not?!

I just finished my ZL-1 last week. I bought the same block, they are up to $5,200 now, I bought mine in March when they were 5k, I had a 10 percent coupon from autorama and it saved me $500.

The blue freeze plugs are the older ones, new are black. Make sure your engine builder checks the line bore, they had an issue in the past.

The 163 intake is the same as the 198, without the divider cut down. I found my 198 for $350. The correct 074 heads are $2,500 done, minimum.

I had pistons made by diamond with 11.5 compression to run on 93 octane, no issues at all. Mine made 550 with a solid cam and cast iron exhaust manifolds, headers are worth at least 50hp on this motor.

Interesting info there....what kind of issues? I bought my block for 4900 from a private person so I can't make any complaints if there's an issue with the line bore! :(
This intake is not an original one...it's the C427X from Edelbrock!
Sound great with that type of power figures....we're going to run this motor with headers from Hooker, like in the old days!  8) ....so you mean that we could get closer to 600 then? Did you run yours in a dynotest?
Pics wanted, of course!  ;D

Have done som cleaning tests on the intake. This is how looked when it arrived, as you remember. But the pics from the seller are little twisted regarding color....the intake wasn't brown when it arrived...




...and after at gentle washing with a low concentrated wheel cleaner with oxalic acid it got a little better:


I then went out and bought oxalic acid in powder and made my own mixture/concentration. Then made some washing again but it didn't make any big difference:




The intake look ok for now, I really want that that old original look and I´m NOT going to glass blast it!
All original threads seems to be ok but we'll see how they really are the day everything is going back on the motor.

Finally the container with goddies for the ZL-1 arrived to Sweden and my hometown!  :P

The first thing to unpack was the crankshaft! As usual we found this used one at eBay for the right price again!
As I understand it this one is identical to the ones original used in the ZL-1 engines and also ised in the L88 engine.
It has the casting number#7115, I understand that the Chevrolet part number was 3967811. Also found some info on the website from Heartbeat City, but I don´t know if it´s correct:

NOS ZL-1 Crankshaft: Many people do not realize GM used two crankshafts for the ZL-1 engines. The early crankshaft shown in pictures features the casting number #3856223. This is a genuine GM crankshaft in the original GM box. The original GM part number is 3967811. The other number GM used, which is more common is the #7115 crankshaft. This is more common and typically was used late in 1969 and for service. This makes no difference as the crankshafts are the same for all intents and purposes. This crankshaft is factory 5140 steel tuftrided and cross drilled heavy duty crankshaft. This is the strongest crankshaft produced from the finest materials in the day.


Our crank is a used one but seems to be in good shape....but that will be a descesion for the engine shop to make when they balance it... ::)

Good, and useful, typical american instruktions for lifting the heavy crank:

Re: The Hugger goes ZL-1....

The collecting of engine parts continues....
There were two other boxes that arrived with the crank... ;D


The heads were extremely well taken care of for transportation, that´s good! But it was a real mess to get every little plastic chip out from all small cavitations in the heads, I promise you!  :P


A big part of an engines character depends of the cylinder heads. As you are well aware of an original ZL-1 from 1969 had the heads with die cast number 3946074, aka the #074. These heads are quite common on eBay but often goes for high prices. It´s strange but if you struggle for the originality they are the way to go and pricing goes in the same direction I guess... ::) Since our effort here is to get something close to original but not a number matching ZL-1 clone so why not go for something more spectacular like a pair of period correct "over the counter" cylinder heads from Chevrolet?

Decision made and the hunt begun...These heads, probably made for racing, has 14011077 as casting number and are often known as the #077-heads. They are not as easy as the #074 ones to find at eBay but if you´re patient you can get some for the right money....and we did!
These ones seems to be in a very good shape as being used parts and also complete with valves and springs.




Both the #074 and the #077 were Chevrolets first heads with open-chambered design. The big difference between these different heads are the design of the exhaust ports. The D-shape, or C-shape, of the #077-head is the major difference. It is said that the #077-heads will get you like 30-40 extra horsepower compare to the #074 ones.....?! :o
Here is a pic where you can see the D-shape clearly:


As mentioned before the #077-heads were "over the counter" and were never standard on any engine from Chevrolet. They were made for racing purpose only. The story is that the special shape of the exhaust port probably was a thing that TRACO, who cooperated with Chevrolet during this period, tested and found out that it worked out great. TRACO got more horsepower out from their engines, maybe due to the heads, than the engineers from Chevrolet and it´s possible that Smokey Yunick got hold of an TRACO Can Am-engine and copied the D-shape ports.

The first series of the #077-heads were made in the mid of the production year 1969 and they didn't come with a cast date number, I've been told. If I look closer at our heads I found some numbers that could be the casting date but I'm not sure how to decode them?
The #077-heads were produced as long as in the 1990:ies....

One of the heads could have been made the 2:ond of October 1974, 1984 or 1994?


...and the other one the 20:th of November 1974, 1984 or 1994?


When ever they were made they really seem to be in an excellent condition. No cracks or welding as I can see. No helicoil inserts and they have never been media blasted or painted either. The valves are stainless and appears to be brand new. The machine work done for the valves must be professionally made, the way it looks. I did a test with red spirit on the valves and they did not leak at all.




The exhaust ports have gotten some small grinding jobs too:


I don't think the light surface rust on the springs will be an issue when the motor is up for assembly but who knows..?

Please fell free to complete the history of these heads or correct me if I have written something wrong!  :)

Any updates?

A few observations. 

The 7115 crank can be found in other engines, even some 366 truck engines had them.

The original GM intakes are not that hard to find, and in my humble opinion would look better on the car if you are going for a somewhat period correct look. But the one you have will be fine.

I have always heard the term "dimple" for those rods, but a dimple is usually indented.  So probably not really the correct terminology. But that is the word everyone I know uses for them.

074 heads are not that hard to find either, if you check with old drag racers. The ones I have were welded on, but received some nice port work and will probably flow just about as good as the 077s. I got mine for under 400 bucks at a swap meet and they just needed the valves lapped.

Hi,
Nope, this is the latest update! ;)
I've some incoming parts from the US but I think they'll arrive middle of Jan earliest!  :-\

As I mentioned in earlier posts we're not going for a super stock ZL-1 here so the intake and the heads are chosen by a purpose!  :P....both economical, period correct and more fun!  ;D
The intake aswell as the heads was more made for racing as I understand it and they will increase the already high amount amount of horsepower that a original ZL-1 has! :P

Regarding the dimple I agree with you....maybe a better explanation is that the surface has microskopic dimples in it due to the surface hardening process from the shot peening?

I didn't say the #074 heads are hard to find, actually there are more of them out there now then before, but they are rather expensive cause of the hunt for originality.....and we think it's more fun and more unusual to build a period correct but spicier ZL-1!  ;)

Thanx for you're observations and I'm glad you joined us here in the thread, keep the posts coming!  :D

No car yet.  Customer just wanted the engine finished then he would look for a car..  I had to make the setup very basic and broad so it would work in a heavy or light car with light tuning..

Finally, the rare pistons have arrived in Sweden and my home! These are some of the most essential bits in my large ZL-1 puzzle!

As I understand it these were factory original installed pistons, #3947886, especially made for the 427 L88 and ZL-1 engines. Rated at 12.5 to 1 with the floating pin design.


We found them on eBay and got them for a very reasonable price also. According to the seller these are the original pistons from a 1969 Corvette with the L88 engine and the car were just driven from the dealer and back home, a trip of about 30 miles.
The original owner removed the engine and replaced the pistons with "Blue printed " stock eliminator pistons while he had the engine built for competition use in the NHRA Stock eliminator class.
They have been in storage in a box in a clean dry garage for all these years.

Of course all this could be crap and an eager sellers best fake argument but so far nothing points to that these "facts" are wrong. The pistons shows the typical signs of ageing and storing for a long time and they all seam to be in a great condition!




The hand made markings from the seller are probably the weight of each piston in pound. All the moving parts in the engine will later be fully balanced and weight adjusted. ....that's another piece in the ZL-1 puzzle.

Thanx Bullit,
Another advantage with these original pistons is that we can rebore the block and buy new pistons without changing the cylinder liners! And they don't make this original dimension of the pistons anymore, just 0.030 and the block can't handle anymore then 0.040 bore so..... :P

Well, I just got some new parts in to Sweden shipped from California.

First a real heavy duty harmonic crank balancer,  a 8" x 2 11/16" high performance HO balancer. A direct replacement for an original one, as I understand it.



Then a new 168 teeth flexplate from Scat. Stamped from a extra thick 5/32" colt rolled steel plate for extra strength. Features double welded ring gears. SFI 29.1 approved balanced and checked for runout.



Both these parts were taken direct to our motor guy that will keep until we have the rest of the parts for the internal and external balancing.

The crank has passed the very same motor guys sharp eyes and ears and has no cracks or other faults. However it will need some polishing and largest oversize bearings before assembly.

I´ll get back to you later when the other parts from US has arrived to Sweden!  ;)

The blue freeze plugs are the older ones, new are black. Make sure your engine builder checks the line bore, they had an issue in the past.
I checked my engine block this weekend and I do have the black freeze plugs!  ;D
I hadn't unpacked my block when I wrote the first time so I just took the pics from the net.... ::)

Finally a box of candy showed up after a looong journey overseas.....


This is the solution for our problem with running this engine on the quality of petrol that we have here in Sweden/Europe, its 95-98 RON.
We think that the original pistons with 12,5 in ration would cause problem while running on the lower octane. After sweeping the interweb we discovered that ICON had a set of new of forged pistons for original bore to the 427, but with a more suitable ratio of 10,8. We found a good price on them at eBay and now they are here! :) 

Great lookin pistons I reckon:


...and here´s the spec:

Bore: 4.25   
Stroke: 3.76   
Compression Height: 1.765   
Compression Ratio: 119CC-10.8   
Weight piston/pin: 703/141

...getting closer and closer to the final.  :P

Not sure who is doing your engine build but make sure to knock off the hard edges on the piston tops..  Reduces the potential of hot spots.  Also might want to consider coating the tops of the pistons along with the skirts.  Just my $0.02 from previous engine builds.

Pistons look nice as well as all the other parts you've added in the past few months.


Piston from the blue car L78 replacement pistons.  I was wanting to get the car finished and worked with the parts I already had..  Im already working out in my head the next engine build for the car..   :o  Either a tunnel ram'd big cube baby big block or a LS with a Holley tunnel ram with rail injectors and dry throttle bodies on top to the intake..   8)  If I were only rich... :-[

Unforunately Austin, interweb babble doesnt pay the bills..   :-[

Cerakote is the name of the company and they are mainly known for ceramic coatings in the gun arena.  The top of the piston is a coating called piston coat which it helps with the ignition of the heat being dispersed across the whole piston and reduces and in most cases eliminates hot spots or essentially its a thermal barrier.  Very beneficial in high compression and forced induced engines.  The skirts have whats called Micro Slick coating which is a dry friction reducing coating.  Can be used in many different applications.  Next engine I build I want to try some ideas with this coating in other key areas of the engine to free up drag and increase horsepower..  Am I racing in a class?  No but it is more of a to say I did and can do it and it works.  Also have used other coatings from Cerakote for the headers, intakes and other items.  So far it is holding up very well.

Yes off the dome.  It doesnt take much to remove them..  I use a scotch brite pad most of the time.  But if you are afraid of damaging the piston then just ask whoever is doing the machine work on your engine to look them over and a good machine guy will know and do it anyways.

Like Darrell stated the tops of the domes should be "softened" in order to minimize points which can cause pre-ignition. 

before the Coatings came about we glass beaded the piston tops (taped the ring lands with duct tape).
The glass beading gave a dull textured surface on which a nice even coat of carbon would deposit-- giving an insulation, which protected the piston tops.

The D port 077 heads look like the exhaust side of Brodix race heads of the 80's and 90's.

They flow much better on the exhaust than the earlier heads and the exhaust is where most heads need help.

Much harder to get air to flow through a short hard 90° turn much less having to come out of and around a valve head.  Also why camshafts designed staggered offset on dura & lift..  Its all in the combo and what you are trying to accomplish.  Excellent point James.

Treat engines like a big ole air pump..  Dont worry about the fuel side as things..  Figuring out how to get more air in and out are the keys as well how quickly can you get it done..  All this engine talk has me wanting to build another race engine...  Its been a while.  I need to be rich.

Thanx Darrel and James for your input, much appreciated!  :D
I'll make sure to soften the sharp edges of the domes myself before it goes to the engine shop for bore and balancing!
I like the comparison with an air pump as well, makes it easier to understand why engines work well or not! ::)

If you are going to use a non standard Cam I highly recommend calling Dave Crower @ Crower Cams for his custom designed solid rollers with HI-PO lifters (hi pressure pin oiled).

He will want the following car weight and gear ratios, trans type, flow numbers on the heads from .100 lift to .700 every 100.

Another little bunch of stuff has arrived at The Huggers nest.....

First these unusual, I do know why, but in my opinion very cool option...the fender guards from GM. I had a NOS set before and now I found another NOS kit so now its complete to the car.
This new box has never been opened since it was sealed in 1968-69:


.. here together with the other kit:


I also did order a complete, 41 pcs, set of chrome plated valve covers that should be very similar to the original part. According to seller they feature the correct height, positioning of the holes, wire loom stands and brackets, most of all they feature the correct drippers as per originals. They do look good enough for me at least...  :P


Some small but good stuff for the starter as well, heat shield and front bracket.


And finally the new cam from Crane. A 10313 that hopefully will do the job!




Here are some spec for the interested:

Rough idle, performance usage, good mid range HP, bracket racing, auto trans w/3000+ converter, 3800- 4200 cruise RPM, 10.0 to 11.5 compression ratio advised. Good w/Roots supercharger, 15 lbs. max. boost w/8.0 max. compression ratio advised.

Lift: Intake   @Cam 3347  @Valve 569 
       Exhaust @ Cam 350  @Valve 595
       Rocker Arm Ratio 1.7

I like the fender guards... since they help protect your rear quarters from flying bits of 'slower cars' that you've blown past... :)

My '69 Z28 had them on it when I purchased the car in 1976, and remained on it until I removed them for 'cleaning and preservation' a couple of years ago.. (I plan on reinstalling them... if for no other reason than to make Bullitt jealous...  :)

Thats funny Gary. Whats ironic is my car also had mud flaps.... :P
I think between the mud flaps and the day 2 ziebart-ing of my car, it probably saved the body and rear quarters from having to be replaced in the harsh Michigan winters.  :)

Had them, yes. Has them "NO". One day way in the future who knows maybe I will put them back on...

To me, while they do harken back to the 60's when many people ran them, they kinda look grandpa to me now. Kinda like curb feelers, But the vintage low riders like to run those now too. I guess both serve(ed) a purpose, you just have to get over the look  ???

Suddenly things started to happen again.... filled the trunk with stuff and went to my local motor shop:

 
 
Now up on the bench are the crank, rods, pistons, flexplate and the harmonic balancer. Ready to get fully balanced.

 
 
The heads also came with me this time for a checkup and also to remove the two inner springs before breaking the future motor and cam in.
The shop´s going to finish the motor like a short block with the crank, rods, pistons and cam installed and I´m supposed to finish the motor project home in my garage, kind of scaring and exciting at the same time, huh!  ::)
The time frame is not to get the motor done fast, just to get it right!  8)
 
I just have to get a short glimpse of the casting number...

 
 
The original ZL-1 block had #3946052/53. I was surprised to se this new number was ending with a "D", #394605D.
Does anybody know why its a "D" in the end instead of a "2" or "3"? My guess is that there is an issue with the owners rights or similar between Winters Foundry and GM....? Could "D" stand for "Developed"....or Dumbass...or Deamon....or maybe Doomed? :o
 
 
All machinery on the raw casting block is done by Schwartz Machine Company and they also put their own serial number on it:

 
 
It´s a story that the operators at Schwartz wanted to make a tribute to the famous ZL-1 and therefore engraved the head caps and the rear cam plug with "ZL-1"...true or not but there it is:

 
 
Now it´s up to the shop to make as perfect job as possible and ill get back with an update a.s.a.p.  ;)

Well, isn't much happening with the motor build right now but at least our motor shop has started to work with the balancing act! :)
He´s taking our ZL-1 between other projects and that's our deal....we rather go slow and correct then fast and wrong!  :P

Here´s one of the pistons and pin on the scale::




The old dot rods has gotten a deep clean and new bushings. He also has reamed the new bushings to fit the new pins to get correct tolerances. These rods are the type with full-floating pins.




After this each rod will go through a balance act, so to speak:


I´ll try to update here whenever new work is put in by the shop.....

Just a question - did the original floating rods have a pin oiling hole in the small ends ? I've never seen an original ZL1 floater, so I thought someone might have an opinion - or a spec.

I really don't know, Steve but these are probably not from an original ZL-1! The dot rods were used in a range of high performance engines such as the L88, ZL1 and LS7.

Here´s a close-up of the small end if this is what you looking for:

Went to the Motorshop yesterday morning before work and now the balancing act is done! I took the chance to be part of the final adjustments and it was fun though I´ve never seen this before.

First the pistons had to be fully weight adjusted within 1/10 gram. The pics below shows how different pistons had to be adjusted. Theese pistons from ICON were, according to Ulf at the shop, very good for being American parts! It differed 5 gram between all of the them in weight! Like Ulf said; - It´s god raw material for balancing!




Also the rods had to be adjusted within 1/10 gram and here the weight difference were 7 gram. Here they are ready to me mounted with new bearings from Clevite.


Here is the crank, with damper and flexplate mounted, balancing bench. The SFI-approved flexplate from SCAT were internal balanced from factory and Ulf was very satisfied with it.


The figures were 0,0 on the flexplate side and 0,3 on the damper side....not ok at all said Ulf!


After finding the exact right spot he adjusted, read used a drilling tool, the damper a bit and the figure went down to 0,1 which Ulf thought was ok!


Now even Ulf was happy!


This was probably the last update for this year cause other projects is knocking on Ulfs door but we´ll get back early next year for more updates!

We wish you all a Merry X-am and a Happy New Year!

After some holidays, fireworks, and other miscellaneous stuff we actually did some work progress on The Hugger!
The first major step of the heart transplant is done!
 
I started with swapping the cars place in my garage so the Hugger got more space around it for easier access....

 
I did some hours for preparation the day before D-day. Marking cables, emptying the cooling system and taking everything off that shouldn´t go with the 355. I´ll keep the tranny in the car and later bolt it to the ZL-1.

 
The Hedmann headers went out together with radiator, generator and distributor....

 
Off with the cowl hood with help from two Camaro-friends. They are really experienced with this kind of work so I´m very happy for the assistance, cause I´m newbie when it comes to taking motors out from a car. Very educational.

 

 
The motor is out of the car for the first time since it came to Sweden in 2005.
A really reliable and stabile motor lift is a bless this times. Professional tools always make work easier!.

 
The 355 is already sold and will find it´s place under the very red hood of a 1968 SS/RS Camaro.
 
We then pushed the Camaro sideways using simple tire skates and two trolley jacks, went very easy and smooth!.
Now its time for The Hugger to lokka back on it´s time as a teenager cause it´s soon going to be a real man!

 
An empty gap soon to be filled with a new ZL-1! But in the mean time its an easy access for work.

 
...to be continued!

Yes, BULLITT is the name of one of my favorite movies, and my first car was a 65 Mustang fastback= BULLITT65 (he has a modified 68 fastback in the movie).

...now when its getting brighter outside its time for an late update!

I´ve been busy with a lot of other things but a few hours has been spent on freshing up the engine bay and also hopefully fixed a leaking manual steering box.
The heating core has to be changed so that process is started.
Unfortunate the work on the block hasn´t started yet so I'm still waiting for that to happen but I rather wait a couple of weeks extra and get a god job instead of fast and wrong! 

I finally got all my stuff that I ordered in late December early January from different parts of the USA:






This is what arrived this time:
- Crane hydraulic lifters
- Special alu head bolts
- Crane push rods
- Crane gear and chain
- ARP oil pump shaft
- ARP fuel pump shaft
- Cast iron BB exhaust manifolds
- Flowmaster 2,5" downpipes
- Master BB engine bolt kit
- BB frame mounts
- BB motor mounts
- Heater box gasket kit
- SB factory heater box block off
- BB heater core
- Heater core bracket
- Melling oil pickup
- Melling oil pump
- Black oil pan
- BB heater hose outlet cover
- Intake gasket set BB
- D-port BB exhaust gasket set
- BB overhaul gasket set
- Generator pulley
- Crank shaft pulley
- Water pump pulley
- Generator bracket
- Waterpump alu
- Manual steering box gasket kit
- Thermostat 195F
- Fuel lines from pump to carb
- Fan wheel generator
- Positive battery oil pan clip
- Heater hose clamp
- Fan shroud BB

I´m still waiting for parts that will arrive in late June so the engine will not be ready for early season but that´s life...

The radiator just got freshened up cause it look real good and it´s not that old I guess?!


The new motor mounts has also been fitted....NOT that easy to access the nuts beneath the frame there...



I´ll be back as soon as I now more!  8)

Suddenly things started to happen...  ;D

I was invited to the motor shop late yesterday evening by the owner and this is the first thing that caught my eye:


I think this is gonna be great..isn´t it a beautiful? If you look close you can se the extra holes that these aluminium block got due to the fact that they had problem with the early ZL-1 and CamAm engines, they blew the head gaskets in this area.


The block is milled from Chevrolet to avoid contact between the block and rod bolts. I think this not that common or does anybody else now?


Since the block is brand new and we´re using standard dimension on the pistons,he just used the stones when making the cylinders.
A brand new set of stred plates were mounted before action:


The outer most pistons are temporary mounted for checking squisch and decking dimension.


The domes are cosy on the pistons, huh?


We just had to get a cylinder head on so we could check for clearance between pistons and valves and it was ok!
It´s not hard to see that this beast is not an easy thing to get down in the subframe of the Hugger....


Today I got a pic from the engine shop when the top decking is ongoing.


If everything is going our way the motor would be ready for me during next week. Then the block and the heads are cleaned and the crank, pistons, rods, cam gear & chain and the cam are mounted and in place. Then its up to me to complete the rest for the first time in my life, exciting to say the least!  :-\

Finally the ZL-1 block is home in my garage...it actually arrived last Tuesday even though it was delayed due to a broken crank seal.
 
Mot motor shop guy Ulf was generous to lend me his own engine stand from Snap On. Nice gear box with crank for easier and controlled rotation. You just have to love the detailing from Chevrolet on the cam shaft cover from:


It´s a beauty from any angle....


Then we had the positive and negative news regarding the heads...  :D  :( 
Starting with the positive the heads look very nice overall and machine work that was already done on them for the valves was remarkable good! We just bought them on eBay based on just the pics so you really don't know what to expect really.
The stainless valves had some numbers on them that I had to check and it turned out that these valves are really good shit, so to speak! They are from Ferrea and their Competition Plus series! Some times the sun shines on me too...! They are priced almost as much as I gave for just the heads on eBay!  ;D 

The negative was that the valve guides, se below, were made of cast iron and that could be a problem together with stainless steel valves and aluminum heads. We also noticed that the springs were to low in rate and they were missing the bottom cup/locators so we had to order new parts from Crane and that will get us two extra weeks of waiting . 




We decided to go for K-line insert bushings and that work was done after the pics were taken.

Other things that went missing from the block are all the guide pins for the heads, cam, transmisson and the cap and screws for the camchaft.
....when you are new to this type of project as I am it´s a lots of thing to think about so I guess this will happen again before the motor is ready to go back in the Hugger!

Even if everything is moving slowly, suddenly things are happening! :)

The Hugger itself needs some attention during this heart change so I´ve done some work in the engine bay and I finally got the heater box out!




The new heater core from NPD, that I got as a gift from winning as ROTM on Team Camaro, didn´t fit in height even though it was made for a 1969 BB Camaro! That´s not good for NPD...... :(


Now I have to let the local radiator shop build me a new and correct one, We have an original 1969 BB core as a template so hopefully we get it right.
As said here in Sweden: - I f you want something right, you have to do it yourself! :)

The missing parts for the engine has arrived so I've started to do some mounting.
The timing chain and gear, the timing cover and the special cam looking plate are now in place.


The timing cover and harmonic balancer in place...


The heads came back from the engine shop with the new and correct springs from Crane in place.
We didn't put the inner springs in yet due to the breaking in process of the cam.


Other stuff that didn't come with the block are now in place.


Then I started with the beautiful head gaskets from Felpro...


But after mounting a bunch of bolt by hand I realized that 8 of them was too long for my heads...I had bought a special kit for aluminum heads and block  but maybe different heads has this setup of bolts? :(
We had to order 8 new ones and luckily they had them here in Sweden so we had them in a day. I also discovered some thread problems in one the block holes and fixed that before I continued to mount the heads. The new bolts had 6 point heads instead of 12 point but I place them under the valve covers. Now every bolt is tightened correctly with its right torque.


The Melling oil pump has been docked with the adjusted pickup and a spot weld keep the pickup in place.


I couldn't help myself...I just had to test mount the intake just to se how it will appear...! :)


You just have to love how the engineers at Chevrolets put in to these parts...

We´ve had a Midsummers holiday here in Sweden this weekend but I managed to get some hours off to continue the build of the ZL-1. :)

A proper, and hopefully period correct, fuel pump from AC Delco have found its new home:


The aluminum water pump is also in place now:


Since I choose to use the factory installed exhaust manifolds, they went in as well:


Rocker covers made the all the parts getting more and more looking like a real engine!




It´s always something missing so I´m waiting for some parts from US & A to arrive...maybe in the next coming weeks?!

I´m back and I've decided to let go of the ****ty Photobucket.com after their hostile behavior the last months. My new supplier is Fotki.com that I hope will have a more mature business.
While I´m new at Fotki and I've noticed that at some sites, like this one, the pics are larger but I don't know how to scale them automatically yet, sorry!
 
OK, here we go again and I believe we were around here the last time we could se the pics...cause I cant see them anymore either! :(
 
Fuel- and water pump in place together with manifolds and valve covers:

 
Oil splash guard in place:

 
The hotter thermostat for alu-engines in place:

The temp sender unit has after the pic were taken been moved to its correct place in the left hand side cylinder head.
 
Oil filter adapter has landed:

 
The correct and also authentic oil dipstick:

 
Alternator and belt. The screws has been sent to correct black surface treatment.

 
Intake, thermostat housing and fuel line mounted:

 

 
I just hade to put it on, sorry! :)

 
Finally I've mounted the oil pan with the one-piece gasket from FelPro. Very expensive but so nice it fitted and I'm so glad to use this one instead of the old school and not customer friendly 4-piece original gasket!

 
I had to make my own studs while ARP didnt have any set for this FelPro gasket...

 

 
Oil pressure sensor and break-in filter in place together with a transport-mount of the flex plate:

 
Starter with bracket and heat shield in place:

 
...and the dipstick in its correct place:

 
Its getting closer now....! :)

 
...to be continued, welcome again! :)

Looks great Hakan! I wouldn't use anything but that Felpro gasket. They work great for me. I just used factory bolts. They were plenty long enough. I like your stud idea though.

I agree regarding the FelPro but the original bolts wasn't long enough for me, especially the two for the chain cover! This is the 1884R-gasket, which ine did you use?
I wanted to use studs due to the aluminum block, I'm afraid of over-torqueing the bolts and then destroying the threads... ::)

Not at all Kurt and I'm on a pretty slow connection. I love the large pics to see the details. Especially Hakan's. He's a great photographer.

Haken,
 I used the 1884R also. Hmmm. I've heard others have the same problem that you did also. I don't blame you on using the studs on that block!!

Kurt,
As I wrote above I´ve noticed that too, but I really don't know how to fix that? :-[ I think many sites must have like an autocorrect fix for large pics but this site doesn't I guess?
...but I don't really have any upload issues though!  :P

OK, great. But I think there is different bolt kits out there and they all came to be original but I think they differ in length...?!
No, the studs are great, especially when ju planning of taking the pan off a couple of times as I do.!  :P

Thanks!
The heat shield is the one that's in the AIM and was originally mounted on all engines I guess?
Its just a thin metal plate so I'm not sure how efficient it is but I like how the engine designer thought when they made it back in the 60:ies...they knew the solenoid has a place there near the manifold so...

is that a bung for a fuel air mixture gauge?
 Also are you going to put a 4 speed manual or more modern 6 speed manual in it with a stick looking hurst shifter by chance?

Yes! I thought its was called lambda probe in english..?
No! Going to run it with the old TH350 I had before....low stall speed and shift kit.

Hakan,

One good looking ZL-1 for sure. Out of curiousity, why the TH350 instead of a TH400 ? I have a bad mental picture of twisted output shafts and exploding internals after that kind of power metering through it. True, a 350 will hold up to mannerful driving, but wasn't really intended for this kind of duty. Just asking -

Thanks, Steve, appreciate it!  8)
I want to keep the TH350 thats already in the car for several reasons...!
One is money, cause building a ZL-1 isn't cheap anywhere...second I'm not gonna race this car and use sticky rubber so hopefully the 350 should manage with me driving it?!

But you have a point and we have thought about it but for now this is how gonna start!  :-\

Without big tires I think the 350 will do OK. Might want to think about that low rpm converter unless your motor likes to idle at 6 or 700 rpm.

There are a lot of things that we probably have to deal when it comes to getin the ZL-1 back in the car again... ;)

I would recommend saving the turbo 350 and your old motor for another vehicle.
To bad you aren't closer I have a 454 and turbo 400 that got built with a street/strip idea, (10 seconds in the 1/4 on all motor) and then never got installed. I am trying to find a buyer for both...and the search continues.... ::) :P

Destination reached! I think the ZL-1 is starting to purr just being in this situation....!  ;D




..and yes, it´s a famous Vega built in US long time ago but that´s a completely different story! ;)

Well, the engine is mounted on engine dynamometer...first time for me in this kind of situation, exciting!  :P
It sure looks good on pic, huh?  ;D


The most important thing why I put the engine on a dyno is to brake the cam in. We just have the outer springs mounted during this process. There are a bunch of piezoelectric sensors mounted on the engine for early detection if something is going in the wrong direction, so to speak....lets hope everything works all right! :rolleyes:

First we boosted the oil with a portable screwdriver and we got good pressure very quick...something I've done right at least! :)




Next step on the list is to brake the cam in......

Finally the cam from Crane has been broken in...but it didn't happen without any problems!  :(


The starter was the first thing that dint work as is should...one thing that happened was that someone, wasn't me though, mounted the flex plate the wrong way! Then we had to shim the starter a lot of times before we could use it with satisfaction...
The next thing that we discovered was the internal electrical system on this home made dyno wasn't build for these type of BB Chevy engines so we almost blew it trying to start the mighty ZL-1!  :o The owner made a quick fix and then it was almost ok...
This dyno has been adapted for smaller Volvo and Beemer engines with turbos and other cheating parts!  ::)

When we finally got the ZL-1 to run it was just to find out that it didn't run on all eight so we just hit the emergency button! Responsible for this debacle was yours truly, who really is a newbie in engine building and therefore hadn´t adjusted the hydraulic lifters correctly and that caused the engine to NOT run on all cylinders! Do again, do right!  :-[     

We then had difficulties with getting the timing correct, the strobe lamp wasn't working as it should. We tested another lamp but with same result so the next thing to look at was the cables and ignition coil. After a couple of starting attempts we realized that that the reused ACCEL coil from the old 355 finally gave up!  :(
This ACCEL coil had been working great on my 355 so I thought it was ok to reuse it on the ZL-1 in an attempt to cut the budget but that backfired!  :-[  We also discovered some bad cables and the only good thing about this is that these kind of problems are nice to discover now while the engine is sitting in a bench instead of being mounted in the car!  :roll:
The owner of the dyno had an old HEI-distributor on a shelf in deep storage so we borrowed that for further testing on the dyno and it worked ok. :|

When we finally got the engine running on all cylinders it ran very nice and smooth on idle ...you actually could do the comparison with the famous RR-engine where you could put a standing coin on top of the engine and it would not fall! Many thanks to my engine shop that did the internal balancing! :D

After a successful break-in of the cam we took the oil pan down for inspection of oil and particles.... nothing suspicious was found and that felt nice as well. I really appreciate the one-piece seal during this inspection! :)


While the cam was broken in with just the outer springs mounted, the complete set of springs now had to be in place. To get the tight spring rates and height we realized we had to order new retainers from USA and of course that delayed the whole process again..
When this parts had arrived and mounted together with all the springs we had to adjust the hydraulic lifters once more..piuuh, its a lot of unexpected things to consider when building an engine!  :P
I borrowed a very nice tool for mounting springs though, very handy!





An old and very used HEI-distributor, not mounted in pictures above, together with almost home made ignition cables and a carb from the CSB 355 that's not optimal for the ZL-1 are not the best conditions for getting a real deal dyno test of a ZL-1 but we will try to get back here with one when the engine still is on the dyno...  ::) the hours in the bench are running away as well!  ::)

Despite all the hassels we had and while the engine was in the dyno stand we decided to do some runs to se what we could get out of this first engine build of mine!
For you guys that that have been demanding a video, I have to disappoint you, sorry!  :-[
We were too busy to check on the engine and dyne during this test runs so i just have these two short vids on it. Taken with my iPhone 7.

First one from brakin the cam in. The smoke is from the WD-40 I used for protecting the manifolds from being rusty during storage.
https://www.youtube.com/watch?v=FCTeNUntxtg

Second one is from the gauges of the dyno control panel. Our ZL-1 sounds eager and the throttle respond is ok despite the saggy ignition system!
https://www.youtube.com/watch?v=Ycc9ReWjmpQ

The original ZL-1 from Chevrolet made around 376 hp at 6750 rpm, dyno tested by Bill Porterfield, with a similar setup as ours with manifolds, original air filter and alternator mounted. Our goal with this build was to get as close as Chevrolets original ZL-1 as possible but within our conservative budget. Therefore we had a sligthly lower compression ratio, a used Holley 750 carb and, as we discovered during the cam break-in process, a not-so-good ingition system! We do have a more race influenced intake but that aren't always the best way to go.. ???

We put a safety stop at 5700 rpm and we then reached around 420 hp, with the curve still rising....we achieved the goal with a margin!  :P
The torque landed one 544 Nm (401 ft.lb.) at 4100 rpm.

We are very satisfied with the dyna results and with a new ignition system, bigger carb, headers and taking the rpm ut to 7000 we´re convinced that our version of the ZL-1 easily could reach 500 hp!  8)
But the goal was NOT to get as much as possible out of it, it was go get a rather street friendly engine and when I really like manifolds on a ZL-1 I´ll keep it like this... for a while at least!  ::)

The engine is now at home waiting to get back in the Hugger again!

It´s not just a simpel engine swap when you go from a small to a big block...nope, why go esy when you can go hard?  :P

One of these other things is to also swap the heater core. As you all know the SB has its water out- and inlets closer to the center but thats no good when the big block and valve covers are in the way of the hoses.

When we was fortunate to win ROTM here last year I ordered a BB heater core from NPD for the price money.
Do you think it fitted?..  ::) You can see the new core to theft and my old SB core to the right.


I had to let our local radiator-shop make a new one and the only thing we kept was the pipings. It turned out very well i think ut the price money is long gone...  :-\


I was happy to one last time crawl under the dash and install the new heater core...


Hmm, doesn´t the pipes seem to be a bit too short?  ???


Yuup. they are! Back to the radiator-shop for a quick do-right-do-again..here is how it turned out:


Much better! ;D


Besides the heater core I´ve also mounted the correct cable for the starter:


Now I also now the correct place for the minus-cable on a BB:


I also wanted to have both a oil pressure gauge AND the original oil pressure indicator in the dash wired so I have to use this solution:

I just have to update while you guys don´t want to stop nagging me..... ;D

We´ve now reached the critical moment in this project when the engine is going back into the Hugger. The car isn't aware of whats going to happen with it in this very moment:


With the engine still mounted on the frame from the dyno it´s easy to lift it with help from two Camaro-friends and a reliable engine crane:




We moved the Hugger sideways in ny garage for easier access to the engine bay during the surgery...anf of course we used sterile clothing.  ::)


Oh my....  :P


We were two guys watching the engine bay and another running the crane 


Tada, the ZL-1 really fitted but its a tight fit!  ;)


After we mounted the TH350 and engine together we pushed the car back to its parking place for further and smaller surgery!




Here are the temperature-controlled clutch, which was standard on 427 COPO,  and the for 1969 original seven-blade fan mounted:


I couldn´t hold myself so I just had to test mount the carb and cowl air filter...it feels so unreal but even though so right!  8)


A bunch of things still remains do to, but every smal step is a step towards getting the Hugger on its wheels this summer!  ;)

Thanks for the little video! What a pretty machine!!
You may check the next time you need to order parts, I'm pretty sure the correct molded bypass hose (between the intake and water pump) is still available so you won't have to live with that kinked piece of straight hose.  ;) 
Great work and thanks for sharing!!

Well, we´re struggling on with the missing parts for completing the build.....  :P

We realized that the ZL-1 Camaros used the 4-rows radiator with the curved-neck so we did a rebuild of the 3-row big block radiator that came with the car. We think it will be ok with just a 3-row cause the ZL-1 engine maybe needs less cooing and I don't have an AC!? My friend att the local radiator shop once again stepped in a made a nice work on the radiator:


We think we got the angles ok:


With some fresh paint on it and test munting of the new fan shroud it looks like this:




I had to order new fan shroud clips from USA to complete the rebuild since one were broke and the other one missing:




I´ve also finished the work on adapting the down pipes to the exhaust system already mounted on the car.
I started to cut the pipes to get a rough shape of them. Then I made some cuts in different places on the down pipe to rebound the pipes where I needed.
Some bits of the pipes that I don't needed:


Test mounting on car:




It the passenger side pipes that needed most work. Then I took the pipe to my friend who did som welding on it.


Complete with paint it loks factory, huh? :) ..and yes, we had to weld another lambda probe mount while the old one was in the way of the steering gear arm! :(


Before mounting on the car I got hold of very nice pieces of joints and clamps from our local speed shop.

During wintertime it´s a lot of other things do to with the family so I have to sneak out in the garage for my quality time... ;)

Due to the failure of my old distributor I had to order new parts from US & A and they finally arrived the other day. My choice was a HEI from PerTronix and their FlameThower model D71000 with the latest HEI III module and adjustable rev limiter. Got a set of matching cables from Taylor mad to go over the valve covers:




Also got the ugly green gaslinkage return spring:


While my combo of a ZL-1 and a TH350 not are the most common thing to do my old bracket for the kick down cable didn't fit.... :( I couldn't find anyone to buy so I decided to do my own! With some old school paper work I got myself a good looking prototype.


Ludde TMW, The Magic Welder, my pal made one ZL-1 inspired from aluminum.


Did a test fit together with the ugly green thing and it turned out ok, I guess! ;)


..after some adjustment and a sand blast it turned out like this:


Before mounting the HEI I changed the internal springs to most correct ones for my application and set the rev limiter to 7500 rpm! :D


Then I realized that I hadn't test mounted this very masculine distributor in the Camaro, oops...will it fit between the air filter and firewall...?




It did! :) ...and now I realize that maybe the engineers at Chevrolet already planned for a HEI when they made this cowl air cleaner or is just the OEM:s that are done this way?

With the knowledge the the HEI would fit I adjusted the oil pump gears and found a still position for the HEI, mounted the cables and voilá. :D


Sure, it's a lot of lack of space but hopefully it will work.




The radiator has gotten som fresh paint and been mounted in place together with the new fan shroud:


Talking about the shroud you can se how bad it fitted at the top as a "bolt-on"...but after some adjustment I think it will work great!


Also mounted the correct upper hose together with the correct, and quite useless, clamps.



That´s all for the moment, folks! :D

I like your day two Edelbrock but for what you are doing I would use the L72 Al intake. They are not that expensive and they do sell a repop, Your setup just looks so factory installed.

Many thanks for your kind words, Kelley!  :D
I’ll stick with my day two intake cause I like it but I’ll consider your advice for the future...
My goal with the car is that should look almost factory but with modern touches were its not obvious... :P

I agree on both points. Factory intake when possible, but very nice installation so far.

Yuup, been a while but I'm back with a small update!  ;)

One of the ignition cable retainer broke during the dyno-test so I ordered a new complete kit from HBC. It came in an envelope so it just took a week to get here from USA, impressive! It wasn't until I read the AIM i realized they were a total of 6 retainers...


Mounted:




Lower radiator hose with clamps:


Finally mounted the heater box hoses. Many thanks for the guiding from this forum!




Also the PCV-hose got the right clamp:


...and today the battery and new cables were mounted:


I´ll be back asap when something new happens to the Hugger! Thanks for stopping by! :)

keep up the progress! When will it hit the road?

(BTW I think only the early cars had the GM logo on the heater hose, most other cars had the ribbed hoses. *Also -They make a better repo of that GM hose)

Thanks for asking Kelley, but no.  ::)

very cool. I hope many other pics held hostage are freed. Since they are now showing, can you copy and save them differently so photo bucket doesn't have control over your pics?

It´s been a while but here are the latest update for the ZL-1 and The Hugger! It´s been a real struggle just to get the motor up and running again... :(

The first goal was to get the car through the Swedish Vehicle Inspection. It´s a new rule this year and that's that a car from 1969 or older doesn't have to be checked upon any more if it passes this years test..

Our problem was that the ZL-1 wouldn't run after it had been put back in the Hugger. Despite the new HEI-FlameThrower from PerTronix the engine wouldn't run other on the acc pump. Finally my friend and experienced drag racer P-A sugested that we would check for air leaks and then we found a problem! When we ran the engine on the dyno I had a distance block between the carb and intake and I had to remove that when installing the engine in the Camaro. Instead I had bought a FelPro gasket with rivets round the holes but when the carb was torqued the rivets prevented the gasket to compress and seal the space and we got an air leak!   
A new standard gasket was mounted and the engine started directly! ;)

With that problem solved and quick adjustment of ignition and idle I went to the Inspection and hoped for the best..


Maybe you can't read Swedish but the next inspection time is schedules to 31/12 2099!  ;D
You can also notice a rather low CO-level and that's been adjusted after the visit.

With that inspection behind us its easier to concentrate to get the engine to run better. We realized that the PerTronix HEI doesn't work that well with this ZL-1 so P-A lended me his mechanical HEI from his 1969 Chevelle and then the ZL-1 started to roar!  8)


This is how the engine bay looks today and I couldnthelp myself with that decal, It will please someone and make others angry!  ::)




The problem I have right now is that the engine stops when I put it in D or R gear and the engine is cold... :(
Maybe I have to build myself a correct carb adapted to this ZL-1 and cam or maybe even look at the converter? I will spend this summer testing and then evaluate the next step.

Maybe I get back here with some videos cause the ZL-1 is really moving the Hugger in a really scary way I can tell you...specially when reed a little, holy macaroni!  :P

What rpm is your converter dragging it down to? If it is 600 to 700 see if the engine will run that low in neutral. My stock converter in my Chevelle took the LS6 cam down to 600 or so and it would barely run. My CX converterin my camaro comes down to 700 or so and the L78 will idle there.

You can try messing with the idle speed, but may need a different torque converter.

Had a really wild 406 small block one time that was a bear to deal with when it had a stock converter, so an aftermarket converter was installed.

What converter is in the car now?

I have idle at 1000 and it drags down to like 800. It work ok when the engine has normal running temperatur.

I've changed the main nozzles two steps larger and will try tomorrow again.

I really don't know the what converter that's in it right now, it came with the car but it´s not stock. I was told it was a low stall speed converter. I painted it silver cause it was rather odd looking but here it is:

I have never had one but my next one will be from them. I understand you can give them your cars specs and they will curve it for the performance
You want. And the price is reasonable.

Thanks for your answer Kelley, that’s even better then I thought!  ;D
You mean the engine specs like cam card, compression, volume etc?
Interesting cause that’s exactly what I’m considering to to with a new custom built carb based on the original Holley 850!

Nothing to consider, right way to do it ;) Any reputable carb builder is gonna ask for cam specs,gears,weight of car,etc... I will say I have heard nothing but good about the Holley HP line.  One of my friends was telling me they were making great numbers with one on the dyno..right out of the box. Slightly lower then the custom carb,which by the way is a great piece. AND the Holley is a couple hundred dollars less.

Another old friend, who is into big cube SBC's in Cobras, has been running the distributer you have pictured for years. Good unit, supports an 800 hp small block with around 7800 shift points with no issues. I was going to ramble on about setting your curve, when you want it "all in", but John Z's article does a much better job! none the less, this will be based on your cam specs. ALSO, Transmission Specialties out of Aston,PA builds bullet proof convertors. Accurate stall. Once again based on your car and engine specs.Get a SFI rated flex plate! If you currently just have a stock one.

Bty, I'm in the camp that loves your engine bay, great job.

The adds I have seen for PD or DUI said they will take car weight,cam and ect. and curve the dizzy before shipment. I can do it but it would nice to open the box and the paper says total advance, total in at what RPM, ect while getting a good unit at a fair price. If I had a SUN machine I would do it but leaning over a hot motor playing with springs and weights kind of gets old.

Thanks for all that interesting info, I may look into that’s as well. But my intention is to keep the engine close to original so we’ll see... :P
Great to hear about he distributor also and your tip regarding the converter, that’s the next step maybe....and I do have a SFI rated flexplate from SCAT! Haven’t you read the whole thread?  ;D

...and many thanks for you loving the engine bay, that motivates me to keep up the work! ;)
