whats the typical average hp gain with the stage 1 cams? and is this might be a little off the subject but isnt there a certain website that has the complete installation of a PI headswap? thanks

 

it all depends on what all you have done to your car. Anywhere from 15rwhp 25rwhp I would say assuming that is the only modification. it also varys by brand. VT Stage 2 & heads would be my choice...maybe 60rwhp w/that done right
