That said, given you can no longer do the work yourself you may be better off swapping in a complete engine. Your least expensive route is gonna be a 4.0 Disco motor. As I said before there are several breakers in NC, I am guessing you get a complete engine for around $500-700. I would guess around 8 hrs for an engine remove and replace. Not sure what your guy charges.

If it was me I would replace the following during the R&R because it is much faster with the engine on the stand than in the truck.

1. Starter
2. CPS
3. Valve cover gaskets
4. Head gaskets
5. Exhaust manifold gaskets
6. Water pump
7. Radiator
8. Coolant bottle
9. All hoses
10. PS Pump
11. Idler pulleys

Sounds like several of these have already been done, so you could swap between the two.

Given your change in work situation now might not be the time for a Disco with a bad motor, sounds like you got it right so maybe you can resell and make a few bucks.

Good luck!
