Ed Pruss Well been busy studying the cam and lifter problem,ordered in a Melling CCS-1 looks fine. I happen to have 3 new old stock lifter bodies that have an original grind on the lobe surface to go by ,they are probably 50 years old given to me by an old teacher of mine. From what I've seen not surethe re-grinders are getting the grind that is needed for long cam service. Any ideas on what is needed ??
