Question re early Ford speedos. (1940)
Can anyone tell me how many cable revs per mile a 1940 speedo is calibrated to? For example my 100E is 1000 cable revs per mile. What is the equivalent number for a 1940 Ford?
I found an old post by Bruce Lancaster saying most USA cars are also 1000 revs per mile (or 1000 rpm at 60mph) Is this right for a 40? We have to assume correct wheel diameters and speedo turtle gears. Thanks in advance. Mart. |

"1,000 RPM equals 60 MPH, 1,000 turns shows 1 mile on odometer on nearly all USA speedos back to mid-neolithic times. You need of course to start with correct drive gears for your axle ratio and tire size...this can be checked on a chart in the '28-48 parts books." My own '41 Merc is 1000 per mile.
