As Joe says, the BB in the S-10 should not be a problem. What transmission are you going to run and how do you plan to drive this thing?

I assume going to an S-10 frame you aren't building a monster trailer puller or a car hauler so you don't need to consider things like a 14 bolt or bigger rear. If you plan to work a 502 or bigger motor, or even if you plan to push a 396 hard, you'll want a stout rear.

If you are just putting the big motor in for eye appeal, a 10-bolt GM rear should be fine. Otherwise you probably want a 9-inch Ford. There are other options, but I can't come up with any real good reasons for something obscure without knowing more about your intended use.
