It would be interesting to see what the engine codes are. They would tell you the year and application for which the engine was built.
Of course, it STILL might not be conclusive if it was a dealer switch, but it would help to provide evidence. If a 454 wasn't an RPO'd option in '70, then if GM installed it, the COPO code would have to be there, correct? Brian |
