1969 Nova Engine Code

[Keith Tedford]

Even the one Boss 429 Cougar was supposed to have been found according to a magazine article. There were about the same number of COPO Chevelles built as the supposed L89 Chevy IIs and look at how many of them have resurfaced. The engine codes would have been stamped in the Tonawanda engine plant. Stick shift cars came with the clutch installed and the automatics had the flex plate. This was enough to give the engines different codes. The L89 engines would also have had unique codes as well. Then again, GM did do some weird stuff so you have to be careful. I guess we'll just have to wait until some concrete documentation shows up. It would sure be frustrating knowing what you have and people not believing you. Been there.
