Do a google search for mustang gear ratio calculator. You'll find your answer there

Was your stock ratio 3.27 or 3.55?

those cobras came with 3.27s.

Your speedometer will read high by 4.10/3.27 X speed. For instance, when you are actually running at 60 mph your speedometer will read 75. Your odometer will be high by the same amount (about 25%) for the mileage you drive while running uncorrected.
