Should i use this cam or do you guys think it would be to much? its for a 305 tpi 5 speed with 3.08 gears. I would also be running tpis runners and base, and headers with it.

Do you think it has to much duration, says it will make power to 5600 but even with the tpis runners and headers i'm only expecting it to pull to about 5100-5200.

the extra duration is good for tpi cars. and i dont think that it is too much. it should run good. with that cam you will have an asome choppy idle.
