Sounds to me a new kick would be best ...
Looking at what you've got, it's move over the front axle (and "widened" calmini lift), rear axel (currie 9), BL, tcase, and misc other goodies (radios, bumpers, etc). I'd think that transplant into a 16V model kick would be just what you want anyway.
Do you know how bad the "blown" 8V is?
P.S. I think a swap (diesel 2.5, etc) into a "beaten" rig should be discounted cuz you'll do a ton of work and still have "Frames bent, all crossmembers are twisted and tattered, body is rusting bad, etc"
