How to Stop Performance Cam Lobe Disintegration
As of today I have lost 3 performance cams due to lobes disintegrating. Two Comp cams and one Chrysler/cam. All were in the street performance range 284 @.050 and 484 lift. On all these I have diligently used the break-in oils and have run in the cams per the manufacturers'' specs. Both Comp cams didn't last long enough for the break-in. I didn't get 50 miles on either one and of course Comp wouldn't stand behind them. The Chrysler did last about 2500-3000 miles before it gave up the ghost last Friday, 7-24-09. These cams were in a '73 Roadrunner/GTX, 440ci. Do you have "ANY" suggestions as to what an "old" hot rodder can do oil wise? Thank you sincerely.

Your best source for information is the camshaft manufacturer. The break-in procedure is dependent on how the camshaft is manufactured, and if and how the camshaft is pre-treated. The number of failures you have experienced may indicate you have another issue that is contributing to the failures.
