    I put 3.80s' in my sprint...With 235-60-14s' in back a 23 tooth gear got it to within 3 mph (Indicated) lower than actual road speed...

    The gear I replaced had 19 teeth. With the 2.79s' and same tire...It was pretty much dead nutz for accuracy...Overall tire diameter is 25.10 inches for my 235-60-14's...
