Camshaft CCA-12-105-3

Summit RacingSummit Racing Verified Purchase

Purchased product from Summit website. Also purchased break-in lube (per on-line recommendation). Once camshaft was received, Comp Cams is recommends cam receive Pro Plasma Nitriding service from Comp Cams (their part # 1-111-1) for an additional charge. This treatment is to prevent early cam failure by hardening cam shaft. Would have been nice to know this prior to check-out. Also, Comp Cams recommends their lifters with special oiling holes to help prevent lobe failure. This also would have been nice to know at check-out. I won't know for months if cam preforms satisfactorily. At the end of the day, manufacturer should have treated cam with Nitriting prior to sale @ no additional cost. ...read more
