For the love of God...........Fred Flintstone had T.B.I.
He is dead on regarding performance and the perception that they will get better mileage.
It still takes X amount of fuel to make Y amount of power and unless they address distribution , there will be no improvement in fuel economy.
If they used direct port or tuned port injection , you would probably realize some gains in this area.
But they have their carbureted engines pretty well science'd out I think and they would be starting fresh with throttle body injection.
