Does that also apply to crane cams?, I've been reading a lot lately about lobe failures on cranes F246 solid flat tappet cam, people following the run in procedures religiously buy still losing lobes.. is this because they're using inferior metals or what? It makes me very nervous as its the cam of choice for a large chunk of cleveland boys, up to 500hp as you prob know, and its also the cam I'm considering as an upgrade for my clevo from my current 224/234@50 powerboss, if i gave you the specs for an F246 would it be possible copy the specs for a custom grind?
