mgarblik - Maybe.
For me, I am trusting the machinist on this. He told me that he is sure, with certainty, that it is a #5 Clevite bearing issue. He has compared it older style Clevite bearings and modern FM bearings. He has bearings there now, 3", 3.25", standard and 10 under. Also, he has the Clevite rep involved, whom respects his diagnostic abilities enough to come to the shop and now has scheduled a revisit to pursue this as a QC issue.
Also, I want everyone to know that is reading this, that my only request of Butler was to contact Clevite, as a reseller, on my behalf regarding the QC issue. I told them that the local Clevite rep is involved and gave them the contact info of my machinist.
It would be great, if out of this debalcle, Clevite would introduce a more chamferred and/or narrow bearing for aftermarket forged crankshafts.
