GM Racing Hyd. Lifters or Stock LS7 Lifters? Which lifter would be better for 6500 rpm use? I know LS7 lifters are good, but would i benefit from getting GM racing lifters? Are the size of the lifters as far as height and pushrod length going to be the same for both lifters?
I am purchasing a set of TFS 225 cnc heads, with 1521 PAC .700 lift springs. I have the SNL v.X cam with about .650 lift on the intake side already, and thinking maybe i need a little more aggressive lifter? Not sure, what do you guys think?
