Rare Camaro History

[William]

"Under consideration" is meaningless.

Some excellent books that cover the real story on Chevrolets' involvement in racing in the '60s:

Chevrolet = Racing?
By Paul Van Valkenburgh

He worked in Chevrolet R & D in the ‘60s. Chevy had tremendous involvement with stock car racing, T/A racing with Penske/Donohue, sports car racing with Jim Hall/Chaparral. He mentions the real story behind the JL8 option. In the "under consideration" category, the Tech Center built a Z/28 with a Corvette rear axle assembly. Surprise, didn't corner any better than the live axle.

The Unfair Advantage
By Mark Donohue

There is no better source for perspective on what dealing with Chevrolet was like. The Penske/Chevrolet relationship was so bad by the end of ’69 they switched to AMC Javelins for the 1970 season. When their ’67 Camaro race car was damaged in a trailer wreck it was rebuilt with junkyard parts.

Best Damn Garage in Town
By Smokey Yunick

The consummate insider, Smokey was there at the birth of NASCAR and was involved with R & D well into the ‘70s. There are some amusing comments about the Hemi 302. A constant theme throughout the book is how cheap and difficult Chevy was to deal with.

I also have the FIA Homologation documents for the '67, '68 and '69 Z/28s.

Nowhere in any of these publications is the sb 3 x 2 manifold mentioned. And why would it be? Looks to have been cancelled April, 1966, months prior to the introduction of the Camaro. As for Smokey Yunick, he was not partnered with the factory in SCCA T/A racing. The SCCA didn't much want him around either, finding many rule infractions in the Camaros he built. That he had this 3 x 2 intake doesn't mean much either. He had buildings full of factory parts that were never used. Chevrolet may have asked him to evaluate it. Since it was never released for production, safe to say he wasn't impressed.

Sorry for the rant, attempts to re-write history need to be addressed.
