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.
