Is there a way to check for this problem on an assembled short block? I had a shop clean, bore, hone, and assemble a 455 block with a rotating assembly kit from Butler. I am pretty sure it had the FM bearings, but had a cast stroker crank, not forged. Spins pretty easily by hand, but that probably means nothing. Because I supplied all the parts, I doubt if they were checking at the blueprinting level.
