60k are the lifters still good ?
. I have all the bolt on mods: hooker Lts , off road y pipe , cat back exhaust , Ls6 intake , ported tb, slp lid , ram air, stage 2 star clutch , sub frame connectors ect... trying to put 400 hp to the wheels
. Thanks for any info. With a 228r cam you should be right around 400rwhp give or take a few hp.
