They were also known as "Screamin' Jimmy", and a lot of names I'd get banned for repeating here! You'll also find the 2-cycle diesels referred to by their cylinder displacement and arrangement, such as a "6-71" (6-cylinder inline, 71 cubic inches per cylinder), or horsepower rating, "238" (same 6-71, set to produce 238 HP). The 8V-71 is a V-8 arrangement of 71 cube cylinders, in power ratings like 290, 318, 335, and 350 HP versions. The fuel injector nozzle size, max RPM setting and with or without a turbocharger changed the horsepower of the same 568 cubic inch engine.
Then there's the 1,2,3,4 and 6-cylinder inlines, with cylinder displacements of 53 or 71 cubes, a 6V-53, 6V-71, and 6V-92 engine, plus an 8V-92 model.
Then there are the big ones, marine engines up to V-16, with cylinders of 100+ cubes.
Confused yet?
