Part one, Stroker crank smoothing and radius the oil holes. Clearances.

grinding the oil holes and putting a radius on the journals oil feed holes. it is a Scat 9000 stroker crank has .002 clearance. I thought about it being ok but it kept eating away at me. I would have preferred .003-.0035. Book called for .0005-.002 a tad way too tight. So I decided to loosen thing up.
