Thanks for the responses. I'm going to talk to my mechanic and see what he thinks might be the direction to go with this. He has taken the engine apart before so he knows what needs to be replaced. I know the crank and cylinders for sure. Also the pistons were not in the greatest of condition. It sounded as though I would pretty much be looking at a complete overhaul. Since the parts are really hard to come by, I thought swapping engines might be the way to go.
