camshaft break-in

Comp has a solid lifter with a laser-drilled hole to oil the face of the lifter, you might ask them about it. As was said, make sure it starts up right away, and have the engine primed. Make sure it has at the distributor initial timing at least 10 btdc and run it for 20 minutes at 2500 rpm. I have never broken an engine in with the inner springs removed, haven't had cam issues at all. Been lucky, I guess. Comp can nitride a cam for around $120, just a little more insurance.
