[Healeys] Speed Calibration

[npaul72464 at aol.com]

 I don't have any formal tables, but my speedo didn't work for a long time so I used the tach as one.? I found out the following (with the overdrive on):
1500 RPM - 33mph
2000 RPM - 44mph
2500 RPM - 55mph
3000 RPM - 66mph
etc.

I found it very accurate.? It now matches my speedo that works and my GPS.? I'm sure it would vary with different rear ends, tires (mine are 165/15), etc.

Now that my speedometer is working correctly again, I need to calibrate 
it against RPM.  Anyone have the table handy that lists Speed vs. RPM 
including gear ratios and tire diameters?

I checked the archives, but no direct hits and I'm too lazy to noodle 
about in there for too long.  This List spoils ya, I guess ;)
