Cams Away!

I believe replacing lifters on a good used cam is totally acceptable. I always inspect my camshaft anytime I'm in the motor and replace the lifter of any camshaft lobe that I don't particularly like the wear pattern of I've only done it a few times. I go through a break-in. Just like a new cam, but I will say I've only flattened one lobe in 40 years and run over 300 lb on the nose on the street. None of my camshafts have been ground since 1990 that may have something to do with their longevity I don't know. I am no way saying that a new lifter can remedy a bad cam lobe! But if I have one lobe whose pattern seems to be a little bit wider than all the rest I will replace the lifter I did this on camshafts that I thought were gone but I guess I caught him early enough because a few thousand miles later when I opened it back up it looked good. I have put new lifter sets on good old cams with success.
