Along with the shorter throw crank the 351m also has taller pistons to account for that. but ya other than the pistons and crank they are the same. deisel would be more torque and better gas mileage but ALOT heavier. I dont know if your going to use this truck for any serious off roading or not but if you are personally i wouldnt go diesel. the dry weight on a powerstroke, just the engine, is over 900lbs. but i cant say as far as the swap goes. someone else would have to chime in for that. I personally am going with a built 351M in my 94 F150.

well if thats all your gonna do with it than diesel might be a good consideration for you, depending on how much work it would be. You get a good 7.3l PS and you treat it right, that thing will last you forever. i know a guy with over 500k mi on his still getting 20+ mpg. unlike gassers which will wear out by 200k. but along with the swap you might want to go atleast 3/4 ton suspension to hold the weight of the engine. I saw a pic of a bronc that a guy put a 12v cummins in on 1/2 ton springs, the truck was lifteed 6in, the back looked it, the front looked like maybe 2in.

So a powerstroke swap would be more economical and efficient then a 460, but would I be able to just bolt one on to the c6 auto and not have to fab something? I don't have the room or the skills to fab motor mounts, ect.

No, on the C6 mating to the PSD. Again, fabrication or transmission swap would be needed. The 460 is the most common swap for these things. If you look around, there are all sorts of "460 swap" articles and parts available. JBG alone has an entire section of their site devoted to this swap. Heck you could find a donor truck with an EFI 460 in it and make a huge leap forward in fuel metering and control. Just be sure to take every piece of the wiring and all fuel system components as well.

Compared to a carburated version of the same engine... hell yes. The entire internal combustion engine industry didn't make the move to the more complex system of electronic fuel injection because it wasn't as efficient as the current technology (carburetors). I could start a list of the reasons but its just a generally accepted principle.
