Andy,
Quickly, as I gotta go, Main brg clearance range .001-.0025" so you're
OK
Rod brg clearance is the same. Piston protrusion OK. Suggest you take your
time with the rear bearing slinger seal thingy that's on the block. Its a
bit tricky and centering it precisely on the crank is essential.
Goota go. Have fun.
