You want a cheap bottom end solution you will have an expensive result at the end. All rods should be gauged and crank journals measured. If any problems you have them addressed. Stock, crank, rods, and pistons will go a hell of a long way. None of this can be performed without removing the engine. If there's a reason to be replacing bearings then there's no reason as to why the block shouldn't be torn down 100% and cleaned 100%. Delete the factory oil cooler also.
