As said before the 400 rod is shorter. 400 rods are known for being a weaker rod so I bet that it is bent. If the block checks out a SCAT 9000 crank is pretty darn cheap and alot stronger than the factory crank. A complete rotating assembly can be purchased from SCAT also that has crank, rods, pistons, bearings, rings, and even a flexplate( on some kits) that are quite resonable. Just have to have it all balanced.
