I need to make a decision quickly so any replies are welcome.
I will be running a GT30r .63 A/R on a built block and V8 big port heads. The questions is: should I go with a Helix 264 cam or stick with the V8 cams?
I won't be running AVCS in either situation.
My biggest concern is usable power and lower end grunt. I had previously thought the V8 cam would be my best bet but now am rethinking things.
