When an engine fails due to no oil in it, you must tear completely down to determine the extent of the damage. Then you must rebuild everything -- this involves machine work and percision measuring of all clearances -- even then it is not guaranteed that the engine is rebuildable. That is why it is best to replace the entire engine with a new one - or a remanufactured one. Rebuilding your existing engine (now-a-days) is usually not cost effective.
BTW - The parts that are damaged are probably the rods - pistons - crankshaft - camshaft - and the block. Even if the block is good (which I doubt) those parts add up to a replacement engine.
