Hey, @cruiser, This is a great idea. If the engine is on a stand, you could back a pickup truck with the tailgate open up to the engine stand and put the engine in the back of a truck. Then take it to a machine shop.
HOWEVER, I REALLY like the idea @Super-Cuda had. find a welding service that will come to you. It will take them 5-10 minutes. I also like the idea @DC 340 had. They say that red Loctite needs heat to release it's bond. You would have to do it cold, but if it didn't work, you haven't lost much.
