How far have you disassembled this engine? Is it still in your car? How long did you run it with low oil and oil pressure? The reason I ask is that if you ran the engine for any length of time without good oil pressure then you may have caused premature wear on other engine parts as well. A good automotive machine shop should be able to tell you what shape the engine is in and give you an estimate before doing repairs. If the crank and other parts are badly damaged then it might be more practical to rebuild the complete engine or find another one that's in better shape.
