Obviously not a COPO due to the date of production or did you see the car and find other things that indicated otherwise?
I have read several times that Yenko was in talks with Chevrolet in 1968 to have the factory install the 427. It was further stated that there may, in fact, have been some 1968 Yenko Camaros that had the 427 installed at the factory.
Has this claim ever been proven?
Are there some 68 cars that have documentation proving the engine was installed at the factory?
Any information would be appreciated.

The trim tag told me all I needed to know. It was a Nov of 68 with X codes and D80.
The first known 427 camaro copos are the ZL1's. The first of which shipped last week of Dec of 68. Marlin I believe was referring to iron headed 427 copos which didn't ship until 69.
