Default Re: Flathead Gas Mileage

I am running twin Holley carbs with a big camshaft and mallory electronic distributor , 3 speed with 3:55 rear gear. Around town I think I might be getting about 10-12mpg, but my foot is always in it! If I took it easy it might get 15-17 which I think is pretty good. Two great people that I know on this board are Ken ct and Charlie ny for carbs and bubbas speed shop for the distributor. Those two things are most likely to blame, unless you are like me and can't get enough of the sound of our Flatheads! lol....
