There was at least one company that made a unit that closed in the pan area so it was separate from the flywheel and provide a 3 speed transmission in place of the planetary. Other examples are when used as a stationary power plant, they would come with a pan and clutch assembly, marine application, the planetary was replaced with a clutch and sliding gear transmission. Some of the bigger names in the Model T racing cars built their own units, not cheap and requires time and money. Once you close in the rear of the engine, you do not have to run the magnets, flywheel and coils in oil. For cost I would go with the Model A, but for cool maybe 26-28 Chevrolet with it's over head valves.
