I know the truck pretty well. Truck is paid off he owns it free and clear. It's his second one. First one got wrecked right in front of our houses. Someone ran a stop sign and T-boned it. Truck was very well taken care of up until the motor started knocking. He has all paper work and receipts for all the work done to it. Never known him to beat on the truck. Pulling the motor and breaking it down is not an issue for me. Been 20 years since I put a motor together. Speed shop In Danbury CT called "Danbury Competition" would be tapped for the machine work. I've used them in the past. I would do the assembly. I was thinking no more then $5k for the truck. Considering I know the history. I have been looking at used engines. Still an unknown till I fire it up. Would rather rebuild the original motor. Then I know what I have.
