roller rockers just curiouse, a buddy told me that if i replace the rockers i could free up 15 to 40hp. is this true and i would also like to know what the stock ratio is on a 2002 ls1 z?
Stock LS1's already have roller rockers. They do not have the roller tip and that won't free up that much HP. The biggest gain is from the roller fulcrum, which you already have.
