I did a search and found two vague responses. So, I need to ask... :
Does anyone know the revolutions per mile a 1964 Studebaker speedometer would have? I'm told it is often printed on the speedometer face..., but below the bezel. So, if anyone has one taken apart perhaps you could look.
A common number is 1000 revolutions per mile, but not all speedometers hold to this. Without this number being correct, the many calculators I have found become inaccurate, - regardless of providing the tire size (diameter) and axle ratio.
The application is a 700R4 behind a Chevy 350. The rear ratio is 3.07. The tire size is 225-60-16 (26" diameter).
Thanks, Tom
