Then it is worth saving. You should take a look at all the main bearings (inserts) and see if non of the locating tabs have been smashed in. (at the edge there should be a notch pressed out and there is a corresponding notch in the block) If they have been you should have it align-honed, if not it shouldn't be necessary unless you use ARP's. If you ran with out oil long enough the seize the b-shafts chances are there is damage to the crank and it will need to be turned. You might want to consider reading a book or two on engine building.
