I picked up a 6.9 a few months ago that has less than 100K on it. Last week I started the swap. Im sorry that I am not computer savvy enough to put pix on the thread but I will describe what I have gone through.
First off, if you do not have a good way to hang the engine, do not even try this swap. When I stuck it in the back of my dad's F-150 to get it home, it dropped the back end WAYYYY down. So when you go to put the engine in, your best bet is to try to keep the engine as close to the ground as possible if you are using an engine hoist. In order to do that, PULL THE FRONT END OFF OF THE VEHICLE or at least the core support and grille.
Second. Once you get the front end off, do the obvious and disconnect the stuff for the gasoline powered engine.
Third. Pull the tranny and attachments. Then pull the engine.
Fourth. This is the part that gets tricky. The plates that the gasoline engine mounts bolt to, have to be removed. On my 84, the passenger side was bolted in. The drivers side however was rivited in so I had to cut/pry them out. As soon as you pull the engine, you will see what I mean.
Fourth A> This is kind of an important piece of info. I had the guy that pulled the engine, take the engine mount plates out of the old vehicle so I could use them. Of the two plates (obviously one per side), only three bolt holes lined up. They looked like they would fit at first, but did not and I had to pull the engine back out.
To pull/install the engine, I found it easier to actually roll the vehicle under/ out from under the engine.
Now, all that being said, there are some things you will need to know. I lynched the springs off of the 250 as I could tell they were larger. I also took the accelerator cable and I am glad I did as there is a difference. The doner vehicle actually came with a T-18 or 19 tranny. I spent a lot of time setting mine up for a manual tranny (dont ask why but I like the idea of a manual tranny in the first place) so I could have an OD setup. However, I still run a NP435. Not knowing what was going to come of that, I took a gamble and the input shafts will work with the same clutch disc's.
As far as I am now is the engine is sitting inside of the vehicle and the tranny is bolted up. No wiring at this point.
Post qustions and someone point me to a link to get pix posted and I will try to do so.
