Hey guys, I'm new to Camaros and the forums, recently picked up a 1979 as a daily driver. Originally a 305 car its been swapped to a 350. I'm new to SBC motors, but I was able to easily locate both the casting number and the machine pad with the engine ID. Casting number is 14010207 so I know it's a 350 from 80-85 but it's doesn't identify 2 or 4 bolt main. What throws me off is the engine ID of V0913FSM I cannot for the life of me find the FSM suffix code ANYWHERE. I've looked through maybe 10 different reference pages and nothing. Anybody ever seen this before?
