hi i am working on a chevy 350 4 bolt main and i want to replace the crankshaft but the one that is curently in the engine is 10/20 if i buy a new one will i have to have it turned to the same specs or can i just install it with standard bearings thanks

the old crankshaft is rusted pretty bad and is nicked up and it needs to be ground again so i figured it would be better to replace it thanks for the help blazin72
