Please keep us up-to-date on how this engine-swap goes. I am interested to hear about it. With a few performance mods (exhaust/intake/chip/turbo), a diesel-powered trac has the potential to be not only wicked FAST, but strong enough to pull down a house. My brother had his F250 outfitted with damn near everything Banks sold for his diesel and that sucker would flat out FLY. Taking 2000-3000 pounds of weight off of that truck would have truly made it a beast.
Not to mention that a diesel engine is incredibly efficient, so you could get better mileage AND more power (what we're all searching for in the end anyway).
I'd REALLY like to see some pics, I suspect that you will have to use up every spare millimeter of room inside the engine bay. However, the reliability of a diesel engine would probably worth your trouble if you get it all up and running correctly.
Oh yeah, you could also run BIO DIESEL!! A buck a gallon sounds MIGHTY NICE to me!!
