Diesel engine swap

I have a 1963 F 250 4X4, I got a crazy id a to swap out he engine out for a Cummings 12 valve. I know it would be a big project and that I would need a new front end, rear end, transmission, ect. My question is has anyone here seen or heard of a swap like this fine on a 60's pickup? Also do you think the frame could handle the weight and power?
Any ideas or advice would be appreciated.

There is a guy on here in Oregon who did this in a '64 4x4. It is a beautiful shade of charcoal grey but I cannot remember his user name. TA455HO will know of him I am sure

Yup, very doable. Frame will live just fine, if you're worried about it, just box the frame.

A 1965, I believe.

That's Keith B - Here's his build thread.

You can always jump to the end of his thread for the final result. Very nicely done. Love this truck!

The four cylinder (4BT)version is a good option too, maybe better because it can make big power in a lighter, smaller package. However the 4BT engine can be more expensive than a complete, running, six-cylinder Cummins truck. It is where I live. A re-body of a rusty or damaged Dodge 4x4 is another way to go.

Thanks TA455HO that's exactly what I was thinking.

I heard mention of the 4 cylinder Cummings it's 5" shorter but I am not familiar with it at this point. I will look into it.

Is it better to buy a Cummings out of an old truck or buy a "crate" engine Cummings? If I buy out of an old truck what are things I need to replace/fix?

There's a tremendous amount of info on a site called 4btswaps.com. There's more 6bt swaps on there than 4bt's so it's an excellent reference.

I'm all for grabbing a complete running truck instead of a crate for you get everything you need to swap. 94-95 was best years for a 6bt swap for the t-case is on the same side as your f100 and no computer to mess with but they were intercooled so you have to hack up the radiator support. 93 down had t-case on opposite side so you have to swap front axles. The front D60's from 94 up were kinda crappy as well. Best bet for a front axle is a 90's F250 ball joint D60 price wise. The price goes up with every consideration! There's a lot to consider...

First of all, Not sure what a "Cummings" is - "Cummins", on the other hand, is a world renowned engine manufacturer...

As for the 4BT, it is 10" shorter than a 6BT. If it were me, I would go with the 6BT.

Personally, I prefer the VE Pumped 12 valves (commonly found in '89 to '93 Dodges as well as a myriad of industrial applications).

If you want to buy a new engine direct from Cummins, get your checkbook out and go for it. All of the ones we have done have mostly come out of donor Dodge's (one did come out of a Ford box truck and another out of a case swather).

Why? Are they more dependable? The P pump found in 94+ added quite a few horses.

Injection pump type does not add or subtract horsepower. Fueling rate and supporting air does.

The VE pump can easily push enough fuel for 400HP. If you want to go over 450HP, then you want the P Pump.

As for why I prefer the VE Pump, it is mainly the fact that it has dynamic timing. When tuned properly, the VE will tend to have better manners for daily driving and produce a little better fuel mileage.

Thanks 1972Redneck for the clarification, dang auto correct!! I mentioned earlier in the post of changing my front and rear axles but I'm wondering if I really need to. My rear is a D60 and front are D44's, gear ratio is 4.56 and 4.55 respectively. I plan on using it as a toy truck, driving around, hauling a boat ect. I would be lying if I didn't admit I would put my foot into it every now and then! But it's not going to be pulling really heavy loads.
