Greetings Friends my 52 Mayfair which has Auto Trans has the 327 ci and the 150 hp engine with Thunderbolt on the head and is the original factory motor. However if it came from Detroit with a Stick Shift it had a 135 hp motor and not the HI compression 150 hp head. I believe the 150 was an optional motor for Stick Shift.
