318 Scratch free cam install. The hard way.

You DO NOT want to know how I install them!!!! Where is my grooved cam core?? I feel so dirty! Let’s think about this, we want a correctly sized flat bearing surface? If we gouge or nick the bearing it can/will bleed oil pressure? Have you see how much pressure the lifter bores dump? Is a knick or scratch going to dump enough oil pressure to be a problem? Mine were PERFECT, right up until I had to lube up an old cam with grooves cut in the journals and turn it in. Ham fisted monkey approach? Yep. Find someone to fix the cam tunnel is the correct way. My oil pressure is 30 lbs at idle hot. Honestly what’s more catastrophic having the cam bores “corrected” and having the bearing spinning and covering the gallery or ream your own bearing and dump a small amount of oil pressure?
