I know it's too late so I will leave it alone and wish you the best of luck but I have to bow out with why not a Cummings? You needed a transmission and transfer case any way!
CA has some draconian laws about gas-to-diesel (Again, from what I remember. I doubt highly that a liberal 'go-green!' state would relax emissions laws to make it easier to pollute). Essentially the motor has to be the same model year or newer with all factory emissions systems in place. For Cummins
, that means you could find a common rail and avoid some amount of the emissions pitfalls that you are stuck with for the 6.0, but rules out the 24v and 12v.
There might also be some consideration given that the 6.0 is "original Ford equipment" and all of the parts are already out there, where I'm sure the 5.9 certainly can be done, but is a more involved and perhaps costlier process.
To really have 'all of the opportunities' you need a 1997-1998 Econoline in CA. Lets you have your pick of the 12v, 24v, commonrail, or 7.3.
MY1997 in CA also happens to be smog-exempt if you run a diesel.
