Initial start-up is the most critical time in the life of any camshaft. COMP Cams offers one of the best protective break-in lubricants on the market (No. 103 Cam & Lifter Installation Lube). It must be spread generously on all lobes of the cam, on the bottoms of the lifters, and on the distributor gear when installing a cam. This is the instant protection you need to guard against any premature wear, so don't install any cam without this protection.
