OK, Im not a big ford person, but there are a few sights that may help get you what you want on parts for a basic build/Swap. Rebuiltautoengines.com carries a good healthy selection of engines with a 7/70000 warranty. It looks like a 460 rebuilt from them will cost 1169$. However, if you want to rebuild the origional engine, Flatlander racing Carries the rebuid kit for both the 360 and the 390. Both are 299$ Personally, If I had the time/money, I would probably go with the 460. But, if you lack the vash and truct your rebuilding skills, a rebuild may work out fine and give you a good solid engine. Its your call.
