What happened to the original crank? If it wiped a main you would want to have the block checked and possibly line bored. Same of the old crank broke. If it wiped a rod, then you still have the possibility of metal in the oil passages, which would destroy the new crank in short order if not thoroughly cleaned.
To answer your question, any 1 piece rear main 350 crank should work. Even a vortec crank, as the only real difference is the machining provision for a crank reluctor. Get a brand new crank, or at minimum on that has been turned no more than .010/.010. Most come with bearings.
