Assuming you have the grip to take advantage of the gearing, the 4.08s are probably good for a couple to a few tenths off your 1/4 mile time.
Highway mileage...
With the stock gear ratio, you are at 2,600 RPM in 6th gear at 70 MPH.
With the 4.08 ratio you are a hair under 2,900 RPM in 6th gear at 70 MPH.
You'll probably lose at least a couple mpg highway.
City mileage shouldn't change much at all.
