The Cummins swap would be HARDER to do but probably not more expensive in the long run. I thought about putting the Cummins out of my Dodge std. cab into my Ford CrewCab but I really want to try an IDI.
The cost is not really the issue when you figure in the reliabilty side, not that IDIs are bad but I haven't had to do ANYTHING to my Cummins since I've had it other than adjust the valves which is part of the maintenence protocol. They also seem to get batter mileage but driving style will make more of a difference.
IF you do the work yourself it will be A LOT of fab work, well work period. If you adapt the engine to the trans. you already have there are some adaptors to buy and they aren't cheap. You can also buy motor mounts rather than fab them but they don't give them away either.
If you want to do the wrecking yard method you could use any 2wd tranny that's been available hooked to the Cummins motor and a Ford divorced NP 205 (L.H. drop). Then you have to adapt all of the shift linkage, get, or have made, a short stub shaft/driveline to connect the trans. and X-case and make the crossmembers.
I'm guessing that you don't want to do this much fab work. The SMARTEST thing to do is sell your truck and get a diesel. Any way you go it will take a while to get the cost of the swap back in fuel savings, even at today's fuel prices.
One thing about the Cummins idea is if it was not a good move or not worth it there wouldn't be people making their living off of swapping Cummins 4 and 6 cylinders into almost everything else out there. And making the adaptors, motor mounts etc. to acomplish it.
MY PERSONAL OPINION IS: the Cummins is better but initially much more expensive and A LOT harder to do. The truck I'm getting has a 7.3L turbo with 368K miles on it (which shows how good IDIs are) so I will be forced with making this decision myself when the IDI finally gives up the ghost. We'll see how much I like the Navistar in comparison to my Cummins.
how can anyone talk about a cumapart on this site.
That same 6 cylinder Cummins engine was offered in the larger Ford F700 series trucks, so it can be here.
If I could, (money and time both available) when the engine died, I'd swap the smaller Cummins 4 cylinder in.
Anyone know what price range the 4 cylinder Cummins going for?
I know it was in a lot of the smaller bread delivery, and dry cargo trucks.
But GOD, why bother with all the work, just buy a Diesel!
The 7.3 weighs something like 1100 lbs so you will need to swap front springs also!

Verified 19 mpg city taking off slow as hell the shutting down at red lights, and with the radiator grill blocked flush, no bed cover, "drag shoot" mirrors on I get 24 mpg at 50 to 55 mph on the freeway empty!

Actually Ford owned 5% of Cummins until about '98 and then Cummins bought it back. Don't take the news personally but it IS the truth.
You can/could get a Cummins in the larger F-series trucks.
The "Ford owns them thing" is an "old wives tale" that had some basis in truth, as most stories get started. I've also heard Cummins B ser. engines are made in Japan, that's bunk too.
I hope this doesn't turn into a slam session like it does on the Powerstoke site. There seems to be a lot of people on this site that have a Cummins in their Ford.
I DO PERSONALLY THINK the Cummins is the best diesel you can fit in a P/U, sorry but I haven't seen anything to change my mind. The difference is I want to learn about other brands of diesels as well.
After spending six weeks or so on this site I am getting an IDI, hopefully this weekend. I might even put the dreaded 6.2L GM in my '70 GMC ext. cab 3/4 ton 4wd. I think it's the worst of the big three's diesel offerings, except for their even earlier attempts. I'm not brand loyal to a BLINDING degree, that doesn't make sense to me. I want to absorb as much info. as possible so I can make an INFORMED decision. So far I haven't seen anything better than the Cummins. If you feel different that's fine, we are still in sort of a free country.

i just like the mechanical pump aspect of this section

lol, i wasnt questioning cummins reliablity, just the headaches it would cause to put in compared to putn in a 7.3, like night and day
btw, hows the '94 turbo treatn u? i remember u telln me about it, did you test what i told you, im just curious? lol
