Gearing is stock '38 Plymouth. 410?I drive around town and out in the country at 40-50 mph? The tires are the correct diameter [28-29"]as the original stock tires were. The odometer is right on as I tested against other cars.
If I drive at 40-50 mph constantly, say 100 miles, just highway driving to test gas mileage, It's 13.5-14. Tire pressure is correct.
I've been dealing with this for awhile, so I think everything is in order. Except shouldn't I be getting 18-19 mph?
