How do you close up the clearance on the mains?
That's what they make "shim stock" for. Also, they used to make .002" undersize bearings for this. Before I put the used Merc engine in my '51 I checked the bearing clearances. I did this because I had just grabbed a set of .002 undersize 8BA rod bearings from Rock Auto real cheap. They brought the rod clearances back towards the tight side of the specification. The engine has excellent oil pressure.

I didn't make it to the shop today (Drs. Appt.). I'll get that clearance tomorrow.
