Bottom line, the higher the ratio, the more power (Torque actually) at the rear wheels, also the higher your engine runs (RPM's) and the poorer your gas mileage.

btw - higher ratio is reffered to as lower gearing (geared down) and lower ratio is reffered to as higher gearing ... nice and confusing eh?

example, with a 4.10 gear set, the ratio is 4.10 to 1 so for every 4.1turns of the driveshaft, the rear axle will be turned one time and you will have a torque advantage of 4.1x
On the flip side for every say 10 turns of the wheels, your drive shaft will turn 41 times & your engine has to turn 41 times in high gear (not overdrive).
With a 3.70 gear, your Torque advantage is 3.7 times but now if your wheels turn 10 times, your drive shaft and engine will only turn 37 times. As with everything auto, always a trade off."

-disclaimer, not my words. explanation from someone else
Holy crap thats confusing
BTW: thanks for trying lol
