Need some help for a friend.

He has a 1972 360 in a 72 chrysler that is needing some trans work and he needs a converter.

He needs to know what type of crankshaft is in the 360.

Is it cast or forged?
Internally or externally balanced?

I realize this is not alot of information but its what I had to go by. Also as far as I know this is the original engine to the car..

Thanks for any help to can give..
