First, enlist the help of someone who knows the difference in a motor and an engine. Then set up both engines on repair stands side by side and tear both of them down to a bare block. Measure everything to be sure the undamaged block is rebuildable, clean it all up, and reassemble it with the best parts of both engines. Get ready to spend at least a couple of thousand dollars for a good buildup. Then buy a couple of cases of antifreeze, and never, ever let the coolant get below at least 50% concentration. You have just learned a very expensive lesson in preventive maintenance!
