Here might be a way to go. A very rough 6.0 2000 Chevy truck but it runs. You also have a core of a 4L80e that you could use or sell to recoup some money. Truck has 244K but I don't know if the motor was ever replaced or not. I would go through everything but you have motor, computer, harness ect and lots of parts to sell off.
