Dont have hard no's yet but after i built this new engine and have over 1k mi on it i have started to check fuel mi. The old motor was getting fuel at 325 mi. The new motor is at 302 mi and the fuel guage is just under a 1/2 tank.
That is a lot more fuel and i have a lot of messing around on this tank and was expecting the no"s not to be too good. So far i am very suprised at how much less fuel has been used.

Engine has much better torq, and cruises at 70 mph with muck less effort. So tickled am i over the end result of this project.
