Does anyone.on tonite, have the formula to figure you speed if you know

your RPMs, tire size, and gear ratio???I put a T-5 in my '60 F100 292

and have no speedometer. Also the OD ratio I believe is .74 in this tranny.

'96 3.8 WC...

Bill:

Look at the home page for this site.  Click on "Tech Articles".  Near the bottom of the list is a formulas post.  At the bottom of the page of formulas are ones for MPH and RPM calculations.
