The short andswer is - it might be worth it. As with almost any vehicle this age, condition is the all important factor.
Also note that the 4" lift certainly will require engineering approval in most states, and if it does not have this for your state factor this in.
As mentioned, it should have the LT95 four speed box, and any other box is likely to be shortlived. If it is a conversion from a V8, you should ensure it has the correct transfer high ratio gearing for the Isuzu.
Apart from the usual things with any Landrover this age (rust, rust, rust) and for any car(mechanical condition), some ot the things to look for are:-
1. Loose rivets, particularly on the bonnet.
2. Cracked or disintegrating plastic bits - grille, instrument cluster, trim. Some of these are hard to find.
3. Upholstery - it is probably getting pretty tired if it is original.
4. If it has original airconditioning, make sure it works - no ventilation otherwise, and it is likely to be a big job to fix it. Same with the heater (required for roadworthiness)
5. Make sure everything electrical works properly - in particular the headlight switch and multifunction stalk, these tend to get damaged by fitting higher wattage bulbs.
