do the guys with the 4:10's know how much they reduced mpg?

Doing the math, going from the stock 3.27 to 4.10 would increase egine rpms by 21%. For example, at 65 mph the engine rpms with the stock gears would be around 1900. At 65 mph with 4.10's the engine rpms would be around 2300. I'm not sure how that would equate to gas usage. Logic would tell you that you are using 21% more gas with the 4.10 at 65 mph. I could be wrong. Pearl02.
