Just purchased a 1971 Chevelle needs lots of work but I think it is amazing. Was checking engine to see if it could be original. It has a engine number of T0909CMJ I looked up CMJ says it could be a 1974 350 police, or a 1980 305 this seems like to very different engines and probably not a matching numbers. Casting number is a 3070010 can anyone help?
