I am considering a swap. My vehicles of choice are either a Centurion 4 door Bronco conversion in 3/4 or 1 ton trim or a 3/4 or 1 ton ford 12 pass. van converted to 4wd. these will be for economical daily family use and not towing or hauling as that is what the 7.3 diesel crew cab is for. My questions are whether power would be sufficient, expected fuel economy, ease of swap, and recommended drivetrain specs. I was thinking minimum 4sp auto. or 5sp man., 4.10 or 3.73 gears, and no more than 33s. What do you all think?
