I bought the truck from the GSA with 55,000 miles, owned 3 and kept the best one. 225 slant 6, 4spd, positive track, that I put through some tough places. It was my work horse, that I loved to drive. The short wheel base did everything I wanted. The slant 6 started to knock, wrist pin noise, so I backed off and thought about what to do with the whole truck. I moved in 2017 and brought it with me. 2021, I started an ongoing rebuild. I found a 318 with 55,000 mile and did a complete Edelbrock build. The main bearings for this engine were hard to find, wider the standard. As of 3/30/24, it’s a major project I hope to finish before July.
