Simple explanation:
The very soft material coating that looks silver is very soft babbit material if the crank makes any friction at all it will give some protection for the crank from damage! your bearings look good for that many miles! You should still at least straight edge the block and check to see if you may need a line bore, and mike your crank and assemble main caps and mike everything!
