5.7 rocker arm question
What is the stock rocker arm ratio? Is it possible to go up a little to get a little more valve lift, or would the valves hit the pistons. I know older Fords one could go from a 1.6 to a 1.7 and pick up some horses and torque without having a clearance or valve float problem Is this possible with the hemi? If so, would it help the power much?
