i used to have a 91 camaro iroc z28 and the thing was pure muscle. kinda wierd going to a lite hi tech car. ne ways i can see y the high compression pistons would produce more power, but ywhat would a new cam do. if its only sohc whats the difference bewteen stock, scence only 1 is used for exhaust and intake, would it just make the process smoother or something? and how much gain would come out of that?? thx for info
