57-60 Dodge light duty trucks (I also included W500s, though they are not light duty) used five engines during their run, the 315ci V8, the 318ci V8, the 230ci flat head six, the 251ci flat head six, and the 265ci flat head six.
Below I have pictures of each engine so you can ID your engine on sight, and if you click the link below each engine you will get a page with details about the engine number locations, and what those numbers mean for each engine.
As a basic overview, the chart below shows which engines were used when, and in what trucks.
