You have posted the crankshaft was ground .0010"
don't you mean .010"? I would plasti-gage all the bearings and double check those bearing caps.
Take a look at the new inserts to see if they're
.010" inserts. It should be on the inserts. You should have from .001" to .0015" clearance on your new bearings. Be sure to use a torque wrench
using the plasti-gage. The mains are torqued to 75 ft-lbs and the rods to 40 t0 45 ft-lbs with cotter pins and 43 to 49 with lock nuts. The torque is very important on the mains and rods.
Be sure to use engine oil on all the bearings after using the plasti-gage. The numbers on your rod caps and rods and the main bearing caps should face toward the camshaft. Hal
