i recently bought a 93 d250 for the ext cab for my w250 i have no need for the 2wd trans or the 12 valve cummins. i have a friend of mine interested in doing a cummins swap into his newer ford 250. i was just wanting an idea on how much the engine and trans are worth. engine and trans have a 170k on it does run and drive and all fluids in the truck look good and smell good. now ive seen price listings on craigslist for 12valve motors but nothing for the 2wd trans just wanting some info and some price ideas as well.
