Paid 50 for a full engine intake starter alternator etc. It over heated but never cracked or warped. It cost me about 1800 total to rebuild the engine then sold my 4.0 with 210000 and a thrown rod for 75. My bet is any where from 50 to 100. It needs fully rebuilt in my opinion.
I'm going to drive it till the wheels fall off, put them back on, and keep going.
