Billet ?

I had a Crosley Hot shot crank for a Demo when I taught in the Auto dept at the College. The hot shot was machined from a large round bar. It had counter weights on each side of the rod throws. Theoretically you can get some teeter- totter effect in a crank caused by balance weight location, but a forged crank has stronger metal structure resulting from the forging process. But the hot shots were high reving stock.

496CHEVY3100 The narrow casting seam means it is a cast crank as Double vision said .another sure way is take a small ball peen hamar lightly tap counterweigkt a forged steel crank will ring ,a cast crank will have a thud sound, Note : counterweight NOT the Journal

ChevroletSS What do you mean by parting line and what is the throws

vinniekq2 take a picture of the throws from the end of the crank,looks cast

DoubleVision I always go by, Wide parting line, it's forged.
If it's a single thin seam it's cast.
