Parts needed and compatibility

There's more room under the doghouse of a Dodge van with a small block than you would think. It wouldn't be any, if much harder to get the valve springs off than it would to get the head bolts loose.
As far as the Magnum motor goes, if you can get every piece of the wiring under the hood of the donor van, including the big fuse box and computer wiring, you will be WAY ahead of the game. From what I have read on here and a few other places, there are only 4 or 5 wires you need to identify and hook up to make it run as long as you have all the wiring. I am going to swap a 5.9 Magnum into an 88 D100 pickup and have all of the above-mentioned wiring complete and uncut. I've yet to find the time to sit down and figure it out though. I've got a friend who said he'd print me out a wiring diagram for the 1998 Dodge 3500 my Magnum came out of so I can figure it out. Good luck to you whichever way you decide to go.
