cost effective performance?
general question for the small-block guys, it was suggested to add a set of 1.7 rockers to my 302 for a little more power. do i have to change vavle springs? will this change where my peak power is made? i have an 87 5.0 ho motor bottom end gonna put carb and intake on it. what is a safe rpm limit before vavle float assuming the vavle springs are still in good health? its primarily a daily driver and its goin in a 91 ranger.
