I was going to my buddy house today, and passed this truck. I turned around and looked at it. anyway here are the specs 1984 gmc siera diesel, new th400 w shift kit, np208 10b front, SF 14b rear unsure of gear ratio. Red good paint but there is some rust. Sorry i didnt get any pics. The guy said that the diesel blew up as he pulled onto the highway. He's selling it because he also has a bad ass s10 thats got a collapsed lifter and he needs money to fix it. He's asking 1500 but he said hes pretty negotiable b/c of the blown motor. what do you think EDIT* does anyone know how much a diesel motor from a yard would cost? Or how hard it would be to convert it to gas?
