I looked up that site you gave me Chuck....thanks.
According to the calculator it says at 80 mph with my 28" tires......
3.90 3844 rpm / 2621 in OD
4.11 4051 rpm / 2762 in OD
my present gears 3.55.....3499 rpm / 2386 in OD
Seems like the difference when in OD is negligible ....or not much.
Will the 4.10's really reduce my mileage by much?....376 rpm?
I now get 16.5 to 17.5
Also Chuck do I really need to get the Posi Unit? ....I'm not going to be
racing or pulling hole shots.....I'm just tired of getting my ass kicked off a
light.
Thanks
Bob
