The wheels on a lifter are an incredibly hard Rockwell. If the cam is too soft it will eat right into the lobe, you can see the sunken track real good on that one lobe. If the heat treat is OK, too much spring pressure. Work with the next cam supplier on the perfect spring pressure for the application.

Next rebuild, go with a better cam grinder... Cam Motion, Texas Speed... and go with their best cam core material.

I'd pull it completely down, there is going to be material embedded in the bearings - mains/rods/cam... pump will be scored... freshen that whole thing up. Talk to the cam grinder at Texas Speed, he'll explain all they do to avoid grinder burn. I would have the lifter bores bushed too. After a cam failure some of those lifter bores may be less than perfect. At least check them all with a snap gauge to make sure no taper, and approx .001" lifter to lifter bore clearance.

Thanks for the advice. I'm likely going with tsp or cam motion either way. My tune is by pat g and I'm trying to get cam specd by him now. . I'll post up some pics as I go.
