I am guessing that they put all of the rods on backwards and the scuffing is from the chamfer on the crank.

Try to post pics of main and rod bearings. Motor has only been spun by hand.

last of them. Normal or problems?

How much force did it take to rotate the assembled short block?

The minor scuffing does appear to be from tight bearing clearances or out of shape journals. First mic the bearing surfaces of the crank mains/journals/rod big ends and the assembled bearing shells to determine the existing bearing clearances. Some of the scuffing appears to be caused by poor housekeeping (debris) or mishandling the bearings. If in spec, clean the main and rod bearing shells, lightly Scotchbrite the obvious scuffs, assemble with a quality moly paste assembly lube, and be sure to prime the engine's oil galleries with a priming tool thru thru the dist. hole.

Seemed to spin easy, major reason we tore it down was to 0 deck the block as the pistons were too far down the hole.

Mains are slightly out of round when checked with a bore gauge so we are now line honing the block, crank measures different any place you check it so it is now being .010/.010, and the big rods all measure different so we're redoing them. Every component has atleast 1 issue, even the block which was bored and honed has a .005 taper in most holes.
