Needing to know a bunch more information to give you an accurate price.
My buddy bought a beautiful '97, clean, low miles, lifted, tires, wheels, HT/full doors, AC, etc, and he paid 4500 for it because it needed a motor. He's a mechanic, and found/installed a motor for under $500. It took him 6+ months to find a good/ cheap motor.
On the flip side, a high mileage, low optioned rust bucket, with unknown additional DT issues, that you would have to pay a shop to R&R a motor in wouln't be worth 1/4 that (if anything) in my opinion.
