Gentlemen, how much HP can one expect from a standard LT4 Hot Cam kit w/o Headers? As in Cam and stock exhaust manifold... Thanks for the info, I enjoy the knowledge!!

 

I wouldnt even think about a cam if I didnt have headers. You will put the hot cam kit in and be disappointed if you do that first. There was someone here that did that and was wondering why it wasnt alot faster. Come to find out he still had stock manifolds. Im not saying you wont gain 20hp maybe, but it would help alot to have headers.

 

I appreciate the reply!
