Really ?!?! So what did the factory do, specify all cam journals be ground undersize? Or did they hone the bearings? Or did they just pound in the cams and hope for the best?
I suppose this MM solution is the best if you're sending out a bare block to be done but most times we're already well beyond that stage when we're installing the cam and this solution is pretty much out of the question. There's nothing wrong with scraping or sanding a cam bearing to fit. Personally I don't like the hone idea unless you're sure material needs to be removed from the whole i.d. but in most case its usually hung up on a small area.
