Jerry-looks like a 71-series-either a 3 or 4, depending on number of cylinders. Looks to me like it's probably a 3-71. the 3 denotes # of cylinders and the 71 is the CID of each cylinder. GM Diesel went on to become Detroit Diesel. The 71-series engine was introduced during WWII. The 6-71 was by far and large the most popular configuration. The 3-71 was often used for generators as well as pumps.
