This is a 1953 Dodge M37, 3/4-ton, 4×4 truck. We spotted it outside of Jack’s Auto Upholstery in Healdsburg, California. It turned out Jack was the owner. He graciously showed me around the truck.
The M37 was built between 1951 and 1968, and fitted with a 230 cubic-inch (3.77-liter), flathead straight-six engine which produced 78 hp and, as far as I can find out, about 190 lb-ft of torque. This engine, the Dodge T245, was in production from 1929–1968 and had quite a long stroke. This enabled it to produce a lot of torque but also caused it to throw connecting rods, if the truck was driven much over 45 mph, hence the notice on the dashboard.
The transmission is a 4-speed manual. The truck even has its original radio. Jack’s had this one for just about a year, in which time he fitted, among other things, a 8,000-lb Braden PTO winch, and converted the electrics from 24V to 12V. The canvas tops and interior he also redid, of course given his profession. They looked quite good, as did the whole truck.
It was a pleasure to see. Check out the links below, to learn more about the M37 or Jack’s shop.
