383 crank needed

Thanks KrazyKuda, That will be my next step...........

One just got listed online near by, it says steel std/std 2brl newport and its cheap
I don't know if there's any difference between a 2or4 brl.

I'm waiting to hear back for the casting number of the old crank, are they all interchangable or is he limited to what 383 cranks he can use ?

I'm just hunting for a crank for him, I know nothing about what fits what, and he's not building anything crazy, just mild maybe 400HP or a lil over so a cast crank is fine
