the problem: i have a '03 turd super duty diesel i want to replace. i have not been happy w/ the truck. the solution: i want to replace the turd w/ a '90 or '91 4x4 crew cab dually. i want a diesel, but i don't want a 6.2. i was thinking of putting a 3116 or 3126 cat diesel or possible the newer c7 diesel. our family buisness is dirt work so i am very familiar w/ the 3116 engines we have 3 of them in varuois equipment so the question is do any of yall know someone that has done it? if u do & u got a link or a pic please send it my way.
