My theory is that.......
........a big old honkin' engine, with gobs of torque, does not require that you twist the wrist as much. I learned this when my making the engine on my 850cc LM engine bigger and bigger over time. As I did all the "wrong" things, like bigger carbs, and bigger valves, and bigger pistons, and more radical cam, the gas mileage kept going up---to 48-52 MPG from 40-44 at the start. No one believed it, but that was the way it was.
You use fewer gears, and fewer revs.
