The issue with pistons that have the oil control ring intersect the wrist pins hole is blown way out of proportion. The problem is engine assemblers putting together engines and not using proper techniques when installing oil control ring. A professional engine builder knows what to do, you must use a ring support under the oil control ring. This provides support to the oil control ring where the piston material is missing for the raised wrist pin. Also this support ring should be dimpled to ensure that the oil control ring doesn't rotate and the ends end up in the wrist pin area. I have had two motors that used the 3.40" stroke with no oil consumption issues. Just my opinion...Mac
