    They didn't send me any moly-based lube for the cam so i used a liberal amount of assembly lube (the red stuff.) The more I read about initial engine start-up the more I see stuff about how the cam if very vulnerable the first 5 minutes of running and needs all the help it can get.
    Has anyone installed a new cam without the moly lube and just assembly lube? I'm wondering if I need to tear the damn thing apart just to lube it up again.

    The greatest stuff in the word to have around when you build an engine is Catapillar camshaftt and Fowler Lube. It comes in a small can with a brush and it is stickier than flypaper. You can get it at truck shops that do work on Catapillar engines. It is about 8 bucks a can and I have done about 6 cam installations with mine and still have about half a can left. The part number is 8T-2998. It is designed to stick to the lobes and lifter rather than heat up and run off during break-in. I have not had a single problem with it yet.


    Like to go sloppin' 'round in da mud in a rapid fashion....=)

    I personally love my GM assembly Lube... works awsome. There are lots of options... I would suggest just getting a good brand name or the GM stuff and make sure you use enough. Clevite (sp?) also make some great assmebly lube as does Redline
