Loyd. Physically measure the outer diamter of your rear tires and u can come up with the axle ratio based on your stats listed above. IF u can't calculate it i can. Based on the 76-78 mph @ 3650 i'm guessing the rear axle ratio is close to 4.00. Rather short ratio to expect any good gas mileage
56 Packard and clippers have a small metal tag on the rear axle indicating axle ratio.
