OK, now I'm absolutely sure it's a forged crank engine and should have all the right parts installed - no holes in the flywheel. That sucker is heavy. almost took my foot off when I dropped it coming out. :banghead:
But where in tarnation did the blue paint come from? Early '72 build - last of the forged cranks? Forged crank swapped into a later block and painted to match? Mopar CSI.
