actually, I was talking about the lifter bore centerline over the cam - very important with these cams that use all the real estate available with the mopar sized lifter diameter....if he bushes the lifter bores, then he's set....
Oh, ok. Yes that can be an issue with them also but I have never seen one wipe a cam because of it. If their way off I could see it happening. I have seen them too tight and too loose though.
The XE series Comp Cams is fairly aggressive but not nearly as much as a cam can be for .904 lifters.
