Hello all, I have a 1969 coupe and it currently has a 302 in it and I want to upgrade to a 351w in the future. I have a question. I have been told that pre 1973 351w motors are the best to try and get because the later years are choked down and don't make as much power. I was wondering if this is true? What are the best year motors to try and get or does it not matter?
