402 Big-Block Rebuild, Part 4 - 1967 Chevrolet Chevelle SS Photo Gallery
1. First up is dropping our Lunati mechanical lifters (part no. 70984) in place. Moly paste (included with the cam kit) is used on the lifters to protect them during initial start up before oil pressure comes up. The moly paste also helps to protect the lifter face while it burnishes to the cam lobe. Even though they're called flat tappet, the face of the lifter actually has a slight crown to it. The lifter spins on this crown, on the cam lobe.
