i have a pretty much stock motor.

with the hot cam kit how much hp gains would i be getting with just the cam? how much with a pro port job and cam?

i can do all the work, just not good with estimates of hp gains and stuff.

 

25-40 with the kit and a tune. Cant say as for the heads. Too many variables. What type of heads? What flow #'s valves, who ported them etc.. anyways typical lt1 head cam setups rput down anywhere between 330 being a very mild setup and 425 plus on the wild end. 380 seems to be a common number to the ground out of an le2 package. Hope some of this helped.
