Default Gen V Crankshaft

Can anyone tell me the difference in Mercruiser crank #429-811552 & 429-811551? Is one cast and one forged?

The 552 is forged from a magnum motor and the 551 is cast from a peanut port 330.If the crank is in good shape I would use it in a motor up 450 hp if balanced properly and the rpm's are kept under 5000.
