if i put on lt4 heads and intake and port them how much hp can i possible gain? also whats the best cam for that kinda set up just

hooker headers, y pip and flow master exhaust. and intake so far

i plan on doing a custum chip and a tb maybe and mill the heads what could i expect hp wise and what would u sugest for a cam? thank u

 

Don't do the LT4 heads and cam. It's not worth what you would pay for it. Our intake is fine and untill you start putting down350-400 at the wheels, a new TB is not going to help you any. Look at doing some head work, Jet hot LT's and a CC306 cam for some more power.

 

well i am talking about with a built engine i plan on stroking the block out to a 383
