1964-1974 Tempest/LeMans/GTO Engine Tuning
Has anyone tried comp cams pn. 51-224-4? Preliminary research tells me I may need to machine spring pockets but doesn't say whether it's a diameter or depth issue. It's going into a 67' GTO with the original 72cc combustion chamber, casting # 670 heads with ARP screw in rocker studs.
