The 260 i don't really plan on doing anything with. The transmission for now i plan on using withthe 350 because the 350 doesn't put out much horsepower now. Well technically it doesn't put out any horsepower at all right now, lol. If anyhting i was going to take the water pump and emission controls, and anything else that could be used on the 350 in case of an emergency, but if you are interested in the 260 let me know, it's just sitting right now. I would be happy if you waned to take it off my hands.
