Hedman after - why don't they build them this way?  Perfect fit with zero clearance issues...

Hedman before - no way it would clear the P/S box

Back to my original question and forum topic...

I ended up building my own Super Scavengers and just wrapped up the install last week.  Still a few more bugs to shake down with the project, which is why i haven't posted any progress info.  Used some Hedman 65003 headers as my starting point since I wanted something cheap to chop up for my experiment.  I'll post the fit issues with the the Hedmans if anyone is interested.

Attached are some pics if I can get them to work properly...

Bottom line - watch out for rookie welders with a MIG, some cold beer and too much imagination......

All the input in this thread is really helpful, and I'm getting close to making a decision.  My engine is done, dynoed and ready to install so it's time to pull the trigger on some headers regardless of the choices.

However, now you guys got me obssessing over those M/T Super Scavengers.  I understand they're hard to find and most likely very expensive if you ever do, but I really like the design of them.  It wouldn't matter if they were originals or reproductions for my usage, but they may just have to stay on the wish list until I locate a decent set someday.

Thanks for all the suggestions!  Charlie

A friend of mine had an unmolested original paint 1968 Z/28 long ago (actually belonged to another friend of mine before him).  It was Carolina Blue with the - - paint code and body colored rally wheels, incuding the original spare tire (before he stripped the car and painted it black).  Only one I've ever seen in person with body colored rallies. 

FYI - This was an early '68 Z with the 302 emblems on the fenders.  Charlie
7  Model Specific Discussions / Trans-Am Camaros / 2013 Monterey Rolex / any parking in the paddock area? on: August 13, 2013, 09:49:00 AM
Some of the group members here will be racing in Monterey next weekend, and I have a question for you guys.  Any chance you would have some extra space to park a car overnight near your trailers/cars in the paddock area?

I'm trailering my "barn find" 1967 Corvette (sorry, I know this a Camaro forum) to have on display in the Corvette Coral during the day.  Evidently, they want the Coral cars removed at night due to lack of security or something of that nature.  My car runs and drives pretty good, but has only been driven a couple times since it was revived (after sitting for 20 years in a field of weeds) so I am apprehensive about driving it to and from the track every day (especially in that weekend event traffic). 

Currently my plan is to trailer the car back and forth down from the Pebble Beach area every day, which will be an excessive amount of effort and a pain in the butt if it comes to that.

I was told it could stay at the track if it was parked in the paddock at night, which is secured, hence my question.  I can easily drive the car to the paddock after the days activities and remove it early before the next days events begin.  You can have a spare key and drive it or move it as well.  I realize this is a strange request, but I'm running out of options and time. 

So guys, any of you have room and are willing to tolerate an old faded Corvette near your rigs?  It's a longshot but you never know unless you ask....  Charlie
8  Camaro Research Group Discussion / Mild Modifications / '69Z 302 - current header recommendations please? on: July 24, 2013, 09:56:19 PM
So I am just about done with rebuilding my 302 for my '69 Z and decided to change from stock exhaust manifolds to headers.  I'd like the car to be louder and a few extra HP never hurts anyone.  After researching all the threads I could find on the subject, it seems prudent to ask the group once again what the current best choices may be based on your experiences.  Every time I see good recommendations, I seem to run across not-so-good ones for the same product.

Here are some specs on my engine:
Bored .020 over with true final 11:1 comp ratio (custom built pistons with no block decking)
30/30 solid lifter cam (Comp Cams OEM replacement)
OEM heads with no porting
OEM intake and carb (upgraded to 72 primary jets)
OEM distributor (set up per CRG recommendations)
Roller rockers and a few reliability upgrades
FYI - The car has OEM power steering.

I also plan to keep the chambered exhaust because it appeals to me.  The car typically gets driven locally mostly / a Sunday-Funday cruiser.  No racing or drag strips, but maybe an occasional slip of the clutch to see if the rear wheels can still smoke a little.

I'm looking for an excellent quality product, that fits properly out of the box, and doesn't require mods for my power steering.  My first inclination is to go with Stahl headers, because they built me a couple of sets for my midyear Corvette race cars and were superb, but I have not used them on a street car as of yet.  Also thought about buying some repro OEM style headers because that would be cool, but they seem to be fairly pricey. I've had Hookers, Hedmans, etc. on my street cars which were fine, but not great.

The rebuilt 302 goes on the dyno soon, so it's about time to order some headers.  Any suggestions or comments, good or bad, from recent purchases?  Any new input would be greatly appreciated.

Thanks!  Charlie
9  Camaro Research Group Discussion / Maintenance / Re: 69 1111480 distributor on: July 24, 2013, 09:23:35 PM
Hello Gents,

Just wanted to add some current info on the vacuum advance can for the 480 distributor.  I am almost done rebuilding the 302 for my '69 Z and after some research realized that this was an important part of my engine assembly.  Even though my car ran fairly well previously, I tested the existing B28 vacuum can and it did not function properly (per the specs provided via this forum - Thanks!) and wouldn't hold advance with vacuum applied.

So off to the parts stores I go with my parts number list courtesy of CRG.  Most stores (O'Reillys, PepBoys, Napa, Autozone and a couple small stores) did not have the listed part numbers, but were nice enough to order me an advance based on the application (the only way they really know how to look up parts on their computer nowadays).  Man I miss the old days with parts books and interchanges and spec books.  Of course each one of those were incorrect, with some being B1's, B25's and one with no number stamped in it at all.

While I was at Autozone examining yet another incorrect part, I asked them to see if there was an "1810" in their brand parts list (Duralast) and there was - a "DV1810".  Of course they had no specs on this item but I ordered one anyway - at $11.99.  It came in today and low and behold, it has B28 stamped in it.  Eureka.  Oddly, it didn't even come in a box - only a FedEx bag.

During this adventure I checked some of my other Z distributor vacuum advance units.  Turns out there was a B1, a B20, and another bad B28,  so I ordered three more today when I picked up the first B28.  Sure hope they are the same upon arrival.

Once my distributor is set up on the Sun Machine, I'll try to post the resulting performance (vacuum and mechanical advance stats).

Final comment:  If you think you may need one in the future, it might be wise to go order a couple while they are still available.  Who knows when the supply could dry up....

on a different note, HUBLEYMAN what is with all the black residue on the underside of your deck lid? I have a similar film of black on the underside of mine , did your car have some kind of rust proofing done at one point?

I'm guessing that the inner portion of my trunk lid was undercoated early in the cars life (by factory, dealer or otherwise?) and at some point in time the spoiler and emblem were removed. That would explain why those areas do not have any undercoating on the spoiler mounting hardware instead of them being completely covered with the same goop.  If you look at the inner structure from an angle, you can see more undercoating extending further inside of the trunk lid.  Maybe some soundproofing or undercoating was part of the style trim group?

This car doesn't have any extra undercoating or rustproofing inside of the fenderwells or on the bottom floor pans, other than what the factory may have applied to all productions cars.  Charlie

The studs on my spoiler are the stepped down style just like Johns...  Charlie

Sounds like you guys should do one of your famous time frame / parts info research charts specifically on rear spoiler hardware.....

If you do, allow me to add the details from my mostly unrestored 1969 Z.  It's a 10A of '68 short spoiler NOR car with hardware just like Johns 02D car.

13  Model Specific Discussions / Trans-Am Camaros / Re: Firebird and the Trans-Am series on: July 11, 2013, 10:28:10 AM
Hey Jon,

Just wanted to add or clarify a few points.  The whole heater assembly, wiper assemblies, etc. were completely removed when I first got the car.  The entire metal dash frame assembly was completely cut out and the firewall was marked up in preparation for some cutting but not actually cut yet.  The stock wire harnesses were all removed and a custom fabbed harness was started with a control panel down by the shifter.  Aircraft toggle switches and indicator lights were used for that assembly.  Seemed like the car got to a certain point and then the modification process just stopped.

The two pics with the heater box and other parts installed were several years after I got the car when I was in the mode of assembling the car for some sort of use.  I borrowed all the dash and firewall components from one of my wrecked 68 Camaros.

The rear flares were solid steel and a very strange design for back then.  It was a challenge to get a tire and wheel combination large enough to fit the shape properly.

A very odd car with an unclear history.  Like you said, maybe it will ring a bell with someone who is willing to share their stories about it......... 

Bob,  If I recall the front hubs had five lugs but they were Corvette rotors and not the OEM Firebird parts.  You just can't make them out very clearly due to the feeble pics I took.

Based on a post I made in the 1968 TransAm season discussion, Jon mentioned I should put some info about my old ‘68 Firebird in this category.  This car never made it to the TransAm races so it doesn‘t have an important race history, but maybe it will trigger some race car memories from those of you who were involved way back then.  So for what it’s worth, here you go. 

Unfortunately I only found a few old pictures that aren‘t really helpful, but then again, I always sucked at photography which is why I don‘t take many pictures.  A couple shots are from the early 70’s, and a couple from the later 70’s when I was getting ready to install yet another drivetrain in it.  Hopefully the pictures show up in this post.

This car started out life as a silver ‘68 Formula 400, which the original owner/builder of the car (whomever that was?) attempted to build into a TransAm race car.  Since this car was from Marin County, it was probably just a well-to-do private entrepreneur that wanted to go racing?  I doubt if the car was ever street driven when new based on the condition of the OEM spare parts that came with it at the time of my purchase (early 70’s) and the fact that the speedo cluster only had 35 miles showing on it, but who knows.

As I was told when I acquired the car, it was never finished supposedly due to some rule change in the 68/69 time frame that caused the owner to give up on it.  I didn’t really believe that story because it was set up with a Corvette Independent Rear Suspension, which I always thought would never be eligible for any sort of TA racing.  When I read the recent posts in the 1968 TA discussion about potential use of an IRS, it prompted me to mention this oddball car. 

Early on, I tracked down the speed shop that installed the rear diff (also in Marin) and the shop owner told me his client provided very specific details as to what was installed and how to do it.  They cut out the trunk floor for the fuel cell, rerouted brake and fuel lines,  installed the IRS per his design, and also completed the manual 4 wheel disc brake combo.  So the rolling chassis was “done”…

I believe the steel rear flares were added after the IRS, because the rears were completed but the front fenders only got cut and never finished.  The cut front fenders were the original Firebird fenders, but the car came with a 68 RS Camaro front end as well so maybe the owner didn’t like the Firebird look and decided to change it midstream?  Either way, that seemed to be when the project died off.  The interior was partially gutted and the roll cage was started but never finished, and as the pics show the firewall wasn‘t chopped up yet.

It previously had a 302 engine with a real M22 which ended up getting installed in my ‘67 Z.  Those were the days when I would swap engines between cars just about every weekend and never cared about what was original or correct, only what was more fun. I installed a spare 427 Corvette engine in this car and drag raced it at Sears point for a while.  It was known as the “Vettaker” (Ok, stop laughing now).  By the 90’s I ended up installing a SBC and setting the car up for street use.  It still had the Camaro RS front end when I sold it, which was always good for starting conversations.

Anyways, if you happen to be that rich guy from Marin and have been looking for your old Firebird, it’s probably still cruising around Sonoma County getting strange looks…

Thanks for the letting me share!  Charlie

Interesting note about potential use of an Independent Rear Suspension.  Could it have been Pontiac?

I used to own a 1968 Firebird Formula 400 that was built for TransAm racing from brand new (it only had 35 miles on it when I got it in the early 70's).  It had a Corvette IRS, steel flares in the rear and a 68 RS Camaro front end - perhaps some sort of prototype or private party experiment gone wrong???  The story that came with the car was something in the rules changed that wouldn't allow it to be raced back in 68-69 so it just got stuffed away in the back of a shop.  At one time it had a Chev 302 and M22, which I replaced with a Corvette 427 when I drag raced the car for a short while. I eventually set it up for street use with a SBC and sold it in the early 90's.  The IRS and 4 wheel disc brakes was a very nice combo for street driving and a lot of fun, but it was more fun to watch people do a double-take at the Camaro front end on the Firebird rear body...... 

Always wondered what the true story was behind that car???  Charlie
