2001 f250 engine swap
I have a 2001 F250 super duty 4x4 and my engine needs bearings, its making a knocking noise, my question is can I put a 2015 6.8l in my 2001 6.8l. I know the computer and wire harness are different, but if I pull the intake and exhaust off my old motor can I basically bolt it to the new block or are there differences?

I also have an'01 V10 so am interested too...
I saw where a guy and his dad put a 3 valve in one of the older trucks and told how they made it work. A bunch of guys on that forum flamed them for it. In fact, because of the number of people who were out to nit-pick everybody else's posts, I left that forum a l-o-n-g time ago so never saw any report on how that project held up over time. FTE is way better!
I believe the heads and intakes are specific to each engine; I know the 3V engines have two antiknock sensors in the valley as opposed to one on the 2V engines. Otherwise, I don't know about just exchanging short blocks.
If I remember correctly, the guys who did the swap rigged the intake runner control open and used the 2V throttle body on the 3V engine, but that was maybe 12 years ago so don't trust my memory on that--I don't!

thank you for your response, I've found a 2015 6.8l with 4000 miles, id buy a new intake for that year. Now I just need to figure out how to hook the second knock sensor without running a new computer and wire harness. Any opinion on that?

Yes, I have an opinion on that. You can't do that. If you ran a new wire to the existing computer for this knock sensor the computer would just ignore it because it isn't programmed to read two sensors.

If I remember correctly (see my previous post) they just hooked up one knock sensor. But which one? And if you needed the one you didn't connect, you could be out a very expensive "bottom end" repair on your new engine and you would be right where you are now.
Ford simply would not go to the trouble and expense of a new block casting, wiring harness and control loop in the PCM if the second sensor was not necessary. I don't know how the circuit "works" or if you could parallel or series the second sensor into the existing one.
Like Mark, I wouldn't try it.
