Proper lube upon installation is vital to a cam's survival, especially with a flat tappet. Apply the manufacturer's lube to the lobes, such as the moly-based paste supplied with this Lunati Voodoo cam, and apply oil to the journals. When installing the cam, use a cam handle tool, and guide the 'shaft carefully into the tunnel without banging-up the delicate cam bearings. The cam should slide into place easily and should rotate freely in the bore. If the cam binds, there is a problem that needs to be corrected before moving on. Possible causes of cam binding can be improperly machined or sized journals, a bent cam (run-out), as well as misaligned or damaged cam bearings. The bearings will show witness marks were the cam is binding.
