It was all about promoting brand image at a time in history when drag racing was "hot" in popular culture.

I've never seen any evidence of such a program in 66-67. It would have required substantial effort and cost, and they wouldn't have authorized it just because a person wanted to buy one that way. I would imagine you would have needed solid upper management connections and a 50 car minimum before they'd even consider it.

It's also worth noting that lots of stuff appeared in PR photos that never made it to production.

I believe the 66 yenko stinger corvairs were copos because of the dual reservoir master cylinder. Please feel free to correct me if I am wrong.

Thanks for all the replies, I did win the argument as he said 66 and 67 Chevelles had 427s which I said they didn't from the factory. 1969 would have been the only time that happened with very few built at the factory as a COPO Chevelle.
