And if you are thinking any kind of mileage, there is no comparison. When my '40 first went on the road, I put a good used 250 from a '69 pickup in it with single exhaust, 2.56 gears with a 4 speed and a rebuilt monojet carb. Took the car to the Inliners meet in Columbus '84 with Patrick Dykes. It was nice to get better than 30 MPG!!! Dare To Be Different
