Very easy... Cast have a narrow parting line and forged have a wide one, on the crank throws. Basically like this pic. Cast on the left.

Tap it with a hammer, if it rings, its forged...if doesn't (just goes clunk), its cast.

drop it from about 2 stories high onto some hard surface like a concrete floor.
If it shatters its cast. if it just bends or gets dented its forged.
In all honesty, I think the forged one will dent the concrete.

I have two big blocks cranks in my possession, both for a 383. How can I tell if either or neither is a forged and not a cast crank?
TWO 383 cranks ? .. they are both FORGED !
They never made a cast-crank for a 383 !!
I would BET a fiberglass scoop ON THAT !!!

Get the scoop in the mail.
71 383 2 bbls were cast crank. I owned one last year. It was the only big block I've seen that I thought was completely useless.
