I havent got that far yet. Im not doing the suspension till this july. As long as the engine isnt way too big it will go. Small things like hoods, mounts, and brackets aint gonna stop this ol boy.

I was serious about why they discontinued the 300 straight six. IT WON'T FIT. Hence the 4.2 V6 when the body style of the F-150 changed in 97. You got a plasma cutter, chassis jig, and wire welder? It'll probably go... Hope you're not fond of the location of your radiator and the silhouette of your grill. You'll probably have to rearrange/reconfigure all that. Maybe cut a gap in the middle of your radiator wide enough for the straight six engine to protrude through, then have a local radiator shop weld it back up.

in 97 ford made an F150 and light duty F250, they also made a 97 3/4 ton and 1 Ton in the old body style because the 460 and diesel would not fit in the F150.
I seriously doubt that the frame in strong enough for the diesel's weight and increased torque.
I think you will end up very unhappy

I'm not the one who is trying to do this. I know Ford made two models of F-250, and know exactly why they made them. (I work at a Ford Dealer) That's what I've been trying to tell this guy....

The only extra weight will really be the motor. I have no idea the specs about either engine (i.e. weight, length, height) Arkie seems to be the expert on this part. This is still the prep part of this plan. I posted this here to get all of this kinda of info help. If the 5.9 is alot longer than the 4.6 and not just a couple of inches then this plan will not work and i will either have to do a lot of cutting and supporting or just try to find another motor. I really do appriciate all the help, comments and suggestions here tho.

Im really hoping there is a way to make this fit because if the 5.9 will not fit I am going to have to sell this thing and start all over again. (Biiger and better of course) But this is a darn nice looking truck if you havent check out my gallery to see it.

FAB, you're really going to have to start over, because last time we all checked, the F150 DOES NOT come with a v12 equivalent inside.
That Cummins is obviously 6 holes long and that Triton, while a pig itself around 575 lb's, is only 4 cylinders long and half the weigh or so of a fully ready to run Cummins. So, I'd plan on a foot or more with accessories IF you care to go on.
Also, that 5.4L in that body rates at 350 lbs/ft or torque.....what do you think 600ish will do to the truck and your comfort in the cab?
The 3.9L 4BT1 or whatever its code is might be a possibilty, but I've heard it's not much of a highway engine. Maybe that can be dealt with....or even an Isuzu diesel.....that 5.2L I4 they have in their commercial trucks with 190hp/387tq seems nice, but it is in an F150, in which that 5.4L is already a tight fit....
Or then again, wait for the 4.5L diesel if you just have to have something new.

The 3.9 Litre is the 5.9 with the front two cyl. cut off. It is a four cyl. Pistons, rods, valves etc are all same. Yes it is turbo and can be after cooled to bring HP up even more. They can be found used in Frito lay vans and Bread vans, although I would recomend a fairly new model as they have a balance shaft in them for a smotther Idle. Stock HP and torque as installed in a bread van is about 105-125 HP and 355 and up torque. I have heard of people getting 190-200 HP and close to 500 lb torque. They take the same transmissions and transfer cases that the 5.9 uses. Engine weight is around 700 lbs vs 950lbs for the 5.9.
I have been told by a shop in Montana that they would put a 3.9 in my 99 F150 super cab for about $4000 labor, $2500 for used engine, $3000 for new 5 speed trans including labor. That included plumbing for the aftercooler and getting all gages to work.

Wow, for $10000 you can find a good used 7.3L F-250 and not have to worry about frame fatigue, or componets not working properly.
IMO, you are better off building up the existing motor and trans planting a 4r100 with a proper rear end and a SFA D50 or something, with proper gears if you really want to keep the F-150.
Heck even the 4r70w could be used still if you had proper gear ratios.
