Well I think it's fair and reasonable to make at least one assumption with this particular cam failure.

I'd rule out mistakes on the builders side, all procedures being followed, lot's of experience with flat tappet cam break in, solid reputation, etc.

Any manufacturer will have an occasional bad product, IF that is the case here with Comp. It might not be. If not, and the replacement cam goes flat, then an exhaustive analysis well beyond engine building industry standards would have to be done. That would be very time consuming for all involved, lets hope it's simply a bad cam from Comp. I hope it's not part of a bad BATCH of blanks from the original source that could be impacting a number of manufacturers!
