Why are you trying to ID the crank if you know what engine it came out of? If you are trying to figure out if its a cast or forged crank, you can look at the parting line where it was formed.

One has a narrow parting line, and the other has a much wider parting line where the crank's mold came together. Hope somebody can remember which is which.

good luck
