I never had an engine go down in any of our restorations in over 25 years. Starting 3 years ago we lost almost every engine with rare exception. We had always used Comp Cam Nostalgic series cams for all of our LS6 builds and switched to other brands a couple of times after having issues with Comp. It helped but still lost two cams last year. In our case it has nothing to do with break in or oils. Simply bad material. Glad I am no longer doing them but still have one more to finish.
