A few engine building tools: Most are obvious. Cam install tool can be used with single bolt cams ( SB as shown ) using the aluminum adaptor which has a 7/16" threaded rod on the cam side or that section can be unbolted ( 3 bolts ) and it can be used with 3 bolt cams and dowel pins. Handle is about 15" long and has a "T" on the other end ( not in pic). Angle tool on top of the block is an easy way to see if the head port side angle matches the manifold angle. Cam checking lifter is nothing more than 2 gutted hyd lifters with a piece of threaded pipe jamed between them. Adjustable positive stop on #1 hole.
