I disagree on that; *most Chevy engines* (whether small or large) that are 'blown up' are solid lifter engines that are OVER-revved (usually by inexpert drivers that are unfamiliar with solid lifter engines).

Restoration / Re: Firewall Pad of Choice???
« on: Today at 12:00:15 AM »
Molded all the way. I just removed a cheap flat pad & got the $175 model you looked at and it is WAY better than that flat junk, I gave it a short thought on searching for a parting out car to source a original but that is difficult and kinda like shopping for a used diaper after all these years the pads just do not survive the test of time,,,If I remember I contacted mfr & they did not sell direct, So I made sure I used a vendor selling the best molded unit and confirmed that is what was being purchased then low & behold, they drop shipped it from the Mfr. I can dig out the info when I get home.

MOST of the 302 engine removals were because the engines were blown up, and the rebuilding expense was so great the owner just purchased another V8 and installed it.

Trans-Am Camaros / Re: Big Block road race cars?

My friend, Robert A Christiansen (Bob), ran 427's in his '69 z28 and his '73 Camaro in IMSA GT races and his 302 in TransAm.  He ran 25 sports car races between 1968 and 1978 or so.  His best finishes were 3rd at Daytona in '70? and 3rd at Talladega in '76...   Another friend, Bob Mitchell, ran 27 races between '67 and 81, including Lemans on a team with Cale Yarborough around 1980?.  His best finishes were 1st twice.  Both of those guys bought new '69 Z28s and drove them to their shops and converted them to road racers!   MItchell's was bought with the JL8, while Christiansen bought his car off the dealer lot and then obtained a 'service duty disk brake rear' via Vince Piggins.

you're right Ed, when I didn't have a Rustoleum self etching can to check, I went and looked online (and made a too quick choice).. that one appears to be gray..  How about this one? 
 https://www.zoro.com/rust-oleum-self-etching-primer-dark-green-12-oz-249322/i/G3131974/

I know I've purchased it, maybe from O'Reilly's if not Lowes?

Lowes DOES have the Krylon self etching in green..     (I bought 3 cans last night ...   4.98/can)

PS.  Speaking of the smog pump... and prices..  I've seen/heard discussed cases of original Z28 PN' pulleys for over $700 by themselves!

I was going to tell you that I just purchased 3 cans last night at Lowes, but when I looked it turns out I bought Krylon (#8609); I've used both and there's very little (or no?) difference.   I use this stuff a lot when I clean small metal parts that I'm going to paint later as I believe the self-etching nature of this primer helps to prevent future rust under the paint.

Yes, most Z28's got their engines replaced (and sometimes trans and rears) very early in their life; oftentimes because young drivers not familiar with what happened when you over-extended the rpms on a solid lifter engine!

I had several friends with Z28s in the '69-72 time frame while I was in the USAF (I spent all my free time in the base hobby shop working on my cars - '60 Chevrolet Impala, then a new '70 RR, and during the '71-72 timeframe I bought a solid Henry J body and put first a 283 /PG combo in it, and then in '72 due to the influence of my buddy z28 racers, I bought a '67 302 from a '67 Z drag car and installed that along with Muncie M21 in the Henry J)...  During that time, one of my friends with an orange/white '69 z28 went thru several different rear gear sets trying to beat the local street racers.. from the 3.73 to a 4.11, then to 4.56, 4.88, and finally 5.38 gears!).. :)   The fast fella in the area at that time worked in the local speed shop and had a '70 Nova 396/L78, 4speed that was drastically enhanced!).. :)

After I was discharged in '72 and completed my engineering degree in '74, I bought a marina blue/white '68 Z28 as my play car ( no significant options but had the original drivetrain which ran like a scalded dog!).   Two years later I traded that to a policeman who had just purchased the '69 I own now.   The '69 had all original components as well but the engine needed a rebuild; the advantage to me wtih the '69 was that it had many and some unusual options which I considered a step up in collector value over the 'base '68).   I rebuilt the engine, and drove the car for 4 yrs before garaging it for a 'some year' restoration, which I later decided would have been a mistake due to the originality of the car!

Anyway, William is correct about *most* Z28's even in the early/mid '70's having their mechanicals 'long gone'; most of the Z28s advertised for sale during those years were also 'in name only' (ie. had the badges but not the bones).

Jano raised question about the brake cylinders....

.... I believe just part numbers on the cylinders.

I rebuilt my brake cylinders and have a photo of one of them, although I don't know the significance of the numbers.   Some of these numbers might be a date code??

Trans Am had their 5 liter limit, but as Trans Am lost favor with the factories, and IMSA GT racing began in the early/mid '70's, big blocks were running.   A friend ran a 427 in a '73 Camaro in IMSA GT...  Running against big block Corvettes etc...

I think the two 5/16" lines to the carb can MORE than handle the fuel coming thru the 3/8" feeder line from the fuel pump.  :)

The JL8 option was predominantly for SCCA racers, who KNEW about it, and who could afford it...

As a production option, JL8 included Corvette front brakes. Requires some rare parts to adapt. A production build would have 15" rally wheels. Chevrolet offered a retrofit kit to adapt Corvette rear brakes to the standard 12 bolt rear axle. It was for off-road use only; no provision for a parking brake.

By 1978 that car was nearly 10 years old. Anything could have been done to it. The JL8 option was released to production January '69 and dropped in June. Earliest known build was mid-February '69. If the car was built outside the February - early June time frame, it wasn't built with JL8.

William,   It must be easier for you to 'imagine' someone ADDING a JL8 rear, wheels, brakes etc to a 69 Camaro SS/RS 396/auto, sometime in the car's first 9 yrs, and THEN trading it in on a new 1978 Oldsmobile? (and getting less than $900 on the trade in)???   

I couldn't imagine it then, and can't imagine it now!   which is why I'm 99% certain that it was original to that car...  I don't know what the young owner did to it in the last 40 yrs (but I told him NOT to modify it and to keep it as original as possible with GM parts - rebuilding the brakes), but in 1978 it had all the appearance of a 9 yr old original car without any work having been done to it...

No mention of the date code on the pump (and I didn't see it in the photos), nor the PN on the pulley...   but it seems to be a good value for what is there..
