You are still finger pointing bobs way and there still a chance has nothing to do with him.. Rite? Or Wrong? Is there a chance?

Have to say by looking at that lobe from the roller riding on it starting to fatigue the lobe and give it surface cracks. Probably not hard enough. That's a pretty good picture. FWI I am not sticking up for no one could care less. Have you had it Rockwell checked yet?

One can was checked cam back ok, plan to have checked again, I get. Bob didn't grind the cams, but his spec was given and clearly per this thread I am not the only one with issues, so it is what it is.... The reason I bash on Bob? Well maybe because if he made it right by at least contacting me unwound have stopped long ago... I bought parts from him... He's not standing behind the part he supplied so I will bash him every chance I get, i now have to replace cams, redo valve job and springs, buy new cams, and whatever else is involved with the change I have to make... I can't sell these cams to anyone so they are 1000.00 worth of paper weights... If nothing else Bob should refund me cam cost and I eat the rest of the few grand I'm gonna spend...

So yes Bob gets bashed and will continue to be... I sent a nice email no harsh words... Nothing... Response?? ZERO!
