I have a 350 bored .60 over with flattops pistons, 041 cast heads pocket ported with 2.02 1.60 valves with big springs and pinned studs. 1.5 roller rockers but need to pick a cam. I have two to choose from. A 272TL-6 comp cam or a edelbrock performer plus cam. The performer came in my 350 but I took it out and used the 272TL-6 but which cam will be better low end and its for a street car.
