Well my dad had a D150 shortbed that he put a 383 and 727 into. As mentioned this truck is a shortbed D150 that is that rust brown flat primer paint color. It was formerly a slant 6 and I believe a 4 speed truck. My dad found a 383 and 727 combo out of an old Newport I believe and had a friend make the mounts and drop the engine in. Dad did just a quick rebuild making sure the valves had good seals and a basic tune up and after the engine was in it fired right up. The truck also has dual exhaust and I'd love to have the truck to make it a tow vehicle for my Barracuda. If anyone in the Nortwest Ohio area knows of a truck like this please let me know if the owner is interested in selling.
