Originality / Re: ENGINE LIFT HOOKS
« on: September 24, 2023, 12:48:30 AM »
With the many survivor cars I have certified over the years, the Z28 will have either natural steel lift hooks or painted Chevrolet orange.  Both versions have been observed over the years, and both are accepted for restoration.

Not yet and the customer is okay with installing the 480 in his car for now but that 9H12 is a tough one to find and very rare.  We will keep the search going.

Thanks,

Jerry

I have a customer who is looking for a '68 Z28 distributor, 1111467, he has an original 1111480 9H12 late date he will trade which we have already restored.  The 467 would have to be dated 8B7, 8B8, 8A5, 8A3, 8A10 or 7J3.

Thanks,

Jerry

General Discussion / Re: 1967 L78 Valve Cover Photo Needed, Right side

Thanks for that photo.  I sometimes have a hard time navigating through our site.  I have never inspected an MR coded L78 that still had the original valve covers or smog on the engine.  Very rare and the covers we have for the engine are original and correct.  I wanted to double check since some of the service covers that Chevrolet made in the 1970s also have weird brackets too.

If anyone owns or knows of a 1967 375 hp Camaro with K19, we need a photo of the passenger's side valve cover.  Rebuilding an engine here at CHP and have a right side cover with bracket, just need to confirm. 

Thanks,

Jerry

One more note, I was just telling Billy G. that I just installed a Gardner system on my survivor '68 Z28.  When I bought the car in 1990, the original owner has installed Corvair turbo mufflers when the car was new.  They were the hot lick for performance back in the day, and he was a professional street racer.  I left them on the car until they rotted out.  My buddy talked me into a stock style Flowmaster with cross-over muffler and 2 1/2" dia.  Left it on the car for about 15 years.  it became annoying and loud at high rpms with the factory 4.88 gears.  Can't say the car was any faster with the Flowmaster either.  Last year, I decided to install a Gardner system.  Seat of the pants, the car did not seem to suffer any street performance at all and now I can hear the solid lifters and M22.  Should have installed this years ago.  You can't go wrong with Gardner systems.

I bought two sets of original GM chambered when I was asst. parts manager at Miller Chevrolet in Ellicott City, MD. I purchased my '69 Z28 in March of '72.  What I noticed when the system was new, it was not quite as loud as the systems available today.  Eventually, as the age and 30-40 miles were put on my car, the system did get louder.  I installed another a couple of years later. When I sold this car in 1976, my Z28 had just turned 99,000 miles.  Without a doubt, do not buy any system but a Gardner.  They are by far the best available and only system accepted in our "Legends" class at the Camaro Nationals.

Here's one of the hypereutectic 302 pistons we tried years ago.  Problems and had to stop using them.

Also remembered that Diamond Pistons in Michigan is also making them.  Racing buddy, Ben Wenzel has bought them and they also work fine.  All of these pistons make more power than the originals too.

Two vendors make them, and they are just as the originals.  J&E and CP are the only vendors and are made specifically for NHRA Stock Eliminator.  Both are not crazy money and better quality than the current and old TRW pistons.  The only TRW piston available now is the 12 1/2-1 and have the smaller ring lands, 1/16 and 1/8" oil ring, and you have to cut the dome.  Cosmetically there are much different than originals.

The J&E and CP have the correct dome height and ring lands, 3/16" oil ring and 5/64" top and 2nd ring. They're not thousands of dollars either.  Andrew from Hendrick Motorsports does all of our machine work along with Keith Dorton, brother of the late Randy Dorton.  We've rebuilt and restored hundreds of 302s over the past 25 years and thanks to our sponsorship with HMS we have the best machinists on the planet doing our work.   We are very thankful for that.

If you have questions, you can always email us.  Be glad to help.

General Discussion / Re: Argent Silver/ Krylon dull Aluminum
« on: April 26, 2023, 05:52:49 PM »
The Krylon #1403 dull aluminum is the best out there and spot on color wise, Dave Cunningham who was a trainer at the BASF paint facility here in Jessup, MD also helped with this match and said it's much better to use the #1403 rather than pay more for mixed version.  We've been using it for years.

There was a changed in Feb to a 2nd design L/S tube which was used for the 1968 model year Z28.  The early cars would have the std L/S tube.  I have photos in my fact book showing the tubes.

Gardner, the one and only correct systems and only one accepted in "Legends Certification" at the Camaro Nationals.  Absolutely the best.
