Got a call from the machine shop putting the 59L together. Merc crank, .010 under, mains & rods, 8BA rods, magged, resized, rebushed. The rod journals are 2.1280. The shop says the rod inserts id is .002 to .003 oversize. Is that excessive ? I thought you needed good clearance for the oil to flow through, promoting cooling. I measured the thickness of a bunch of the Ford NOS inserts in the original unopened boxes marked OBA-6211-C, .010 U.S. and came up with .106 thickness. Any opinions ? Thank you Fordbarners.
