Very interesting engine!


I'd say it was a replacement short block for a 64 GTO? car.
I think that a dealer would/should stamp the replacement engine with the original EUN/code?


That engine is actually a Nov 1965 block which they were probably making engines for 1966 model year.

Looks like that eun would be around a 03D car in 1964.
