Am trying to determine the rear axle ratio of my 56 Dodge pickup. It is a V8 with four speed transmission. Am able to do about 60 mph on highway but would like more speed. When I bought the truck in 2005 the seller said it was 3:55, but I am skeptical given the whine/howling at 60 and above. Are there any stampings that would reveal that information (and avoid pulling the gears and counting)?
Many thanks, Lorne
