Use this to calculate from known parameters and engine speed

and here for tyre diameter

we should make these site a sticky this same question comes up all the time

 

I'd say about 110 Ford speedos lie REALLY BADLY

Assuming the tyres are 185/70/13 and you can get the engine to 6000 in top (which i doubt TBH) you'll be doing 116MPH

or if oyu have 175/70 113.

 

Input Parameters Are the Following:

 

* Differential Gear = 3.56 to 1

* Transmission Gear = 1.00 to 1

* Tire Diameter (Inches) = 23.20

* Engine RPM = 6000

 

Computation Results:

# Computed Vehicle MPH is 116
