BB chevy crank question

The cast cranks are bad about cracking when they've been spun badly enough to need to go past 0.030" from standard size, if the rod throw has any real color in it, you're probably better off to find another crank. And check to make sure someone has 0.050" or 0.060" bearings in stock (make them go lay their hands on them) before you pay to have the crank ground that far. Those are not as easy to find as they once were, I'd hate to see you spend $150 or more grinding the crank and then not get the bearings.
