Its a 350 S/B Chevy ..... Run Down to the Local Pigly Wigly and pick up a Re-Man'd Crank Kit & be on your way !!!! Isnt that the EASE of a Chevy 350 ? Easy to Fix, CHEAP, And you can get parts ANYWHERE ?
I thought it would have to be align bored to be of any use and that is too much to spend on this. Am I right?
SBC are a dime a dozen,for what you would spend on a crank kit you could buy a complete runner and be on your way
FWIW, I've seen just that break before. Seems to be a weak spot or related to the oiling pattern. Cosmo
Of course it's repairable, when all others that aren't broke have been melted down and it's the last one in the whole-wide-world.
