Re: Flathead Gas Mileage
I have observed anywhere from 12 to 22 with stock flatheads. The earlier cars seem to get worse mileage. My 85 horse 37 gets about 15 at a steady 60, my father's overdrive equipped 50 got 21 at 70.
I think you should really look at your carburetor jet and power valve settings as well as your distributor advance curve. Make sure you are not running a stock 49-53 distributor with dual carbs.
