ZL1 factored HP and valve springs

Al Loyrat · 02-16-2015, 02:12 AM

I got the CCs at 117 (min.114.5). I want to leave some meat on the heads in case a head gasket pops someday. Seat is 153, open is 410 on the springs. 580/620 lift. Nice to be able to use head studs!

. This engine is complete and in the car. Got an iron short block for back up. I remember Kevin with the orange 69, met him in the pits at Norwalk years ago, nice guy. Jimmy still running the 66 Vette?
