Rare Camaro History
 

Solo Smokey Update Okay found some super cool Camaro history!
Rumor has it that Chevrolet came out with a 3x2 manifold for Trans Am Racing and then the project was scrapped. They were working on this before the first 67 Camaro was made Well I can now document this I pulled off the manifold on my 69 Z28 that previous owner Larry Schreib bought it off of Smokey Yunick himself I flipped over the manifold and could not believe it is dated 2/9 /66 it's all true case solved! Thanks in advance Bill Fowler / Solo Speed Shop

That is way cool! I had read about those somewhere and had always wondered if any/how many had been made. Thanks for sharing!

While you have the manifold off it is a good time to clean it, but don't beadblast it.

I mentioned Dry Ice blasting on Facebook....

That is really cool. Thanks for sharing. I use plastic media frequently to clean parts like this. It take off the dirt and surface corrosion without altering the finish.

Vapor blasting is the way to go these days. David Beem is a site sponsor here and has the latest apparatus setup for proper cleanup.

You can contact him through his bodyshop I think? https://fixautousa.com/location/colorado-springs/

Why would they use a 3X2 setup for Trans Am Racing instead of 2X4?

They didn't.

The 3 x 2 manifold was never released to production and is not listed in the SCCA T/A Homologation documents for the Z/28.

Just because it wasn't used doesn't mean it wasn't under consideration. Engineers try things to see what works best. The 3x2's must not have come out on top.

Personally, I used to run two 650 cfm Holley two barrels on a cross ram manifold in an IHRA drag class because the class record was softer than it was with a single four barrel. Rule books were meant to be read, whether it's Trans Am or drag racing.

Nice rocker arms and headers too!! :beers:
