This engine has superseded the DVT-573 in 1968 (which was produced between 1962-1968, and had a rotary Roosamaster injection pump). It's a compact 573 ci, 4 stroke, V8 turbodiesel. This is a 90° V, with a single polydyne camshaft inside the "V", 2 valves per cylinder, watercooled, and a square design with 4.5 inches bore/stroke. This new engine had a new Bosch V-Pump like German M.A.N D2658 & D2858 type V8 engines (mainly fitted in trucks). We can see applications of this engine on International Harvester engine list.
