6.4 Powerstroke in a 77' F250

[rynodog92]

Just wanted to know if any of you have seen or heard of putting a 6.4L powerstoke in a 1977 F250. Can it be done, will the engine mounts work? Will the wiring even be possible? Just wondering if it was even possible, if so, what parts would be needed? Money is not a concern.

If money is not a concern, then yes, its absolutely possible.

You'd be a lot better off putting an old body on a new frame, I wager.. that is work too, but not as bad as transplanting motors..

That's true. I think the old 77 looks very nice (as well as the 78/79), rather than the newer body looks. Thinking about doing it as a project, although I know it would cost a lot, wiring would be an issue, have to find a different transmission, and even after all being put together if it would be reliable...

Old body on newer chassis would be the way to go. It would give you all benefits of modern engineering like ride quality. You would have to use the complete engine wiring harnes, computer, fuel system, etc from the new chassis. Wheel base might be an issue. However, moving the rear axle to the correct position is not complicated.
I think you could title it as a '77. Then you could legally bypass all the emissions on the 6.4. Sounds like fun to me!

If you drop the 6.4 in the old truck.....you will never have to worry about emissions and the EPA. Just a thought? If you put the 77 on a new chassis, you will be subject to the EPA bullish!t.

That is probably going to be a pretty serious exercise. It's not like dropping a 302 or 350 into an older truck.

The 6.4 is going to weigh a lot compared to a traditional swap and require heavier springs, bigger brakes, and adequate cooling. Throw that on top of making sure the fuel system works properly and that you have enough room for everything would make this all a pretty serious project.

Not saying it can't be done, but I'd be more willing to do something like a 7.3 into an older truck than a 6.4. That motor is a little more forgiving (fuel and cooling) than the 6.4.
