Or just assembling a motor a machine shop has built for you? It's going to be tough if it's the former not the latter. So many things could go wrong and there's no guarantee if you hone an engine in your driveway the rings will seat (then there's a question of if the heads need/should be rebuilt, etc.
I wish you luck though! If you weren't 6 hours from me and my arm wasn't all stitched up I'd lend a hand for the tires ;-)
