Polished the crank with 500 grit and measured main clearances. Had to dance to follow the crankpins. 1-6 are right about .003 on the diameter while 7 is .002 with thrust at .008.
Measured crankpin to deck, all within .001 resulting in the piston proud of deck by .003. Right where I wanted it for .037 piston to head clearance.
Rock the piston with my thumb and the quench side is up .018 and the opposite side up .012. What's the deal here? Another rookie engine machinist mistake, that's what. When I set up the block to machine the deck I had equal packing under the oil pan rail. If I had laid a level across the bellhousing dowels I would have caught the error. Should have shimmed to cut level relative to the dowels or dialed in the bore.
