I would check compression. and then the normal tune up items plugs cap rotor wires TIMING. How bad of mileage are you getting. If its around 8 mpg then thats about normal. I just changed from the c6 automatic to the zf5 manual and gained 4 mpg on the highway, went from 8-12mpg in a stard cab 250 4x4.

find another 7.3l idi w/trans to set in there and double up her fuel economy like your '93 hey?
why would you even think about buying a 460 pig engine with today's fuel prices? at best,they can only get half what the diesel gets.
start to use them,and they get even worse.

that swap is not worth it. You need an entire new fuel system, wiring harness, computer, Tranny, t-case, exhaust, wire up a glowplug light in the cab, possibly have drivelines modified, motor mounts, and im sure the list goes on. If you had a donor truck that is wrecked then maybe, but I wouldnt do it unless it was a completely custom project truck
