1967 help #8

You can change the speedo by putting in a different drive gear in the tranny, but changing it by 50% is asking a bit much. The whole system is mechanically designed and run, so it would not be simple to change the speedo itself. If you could, when it reads 30 mph, it would really be 45 mph. You'd have to do the conversion in your head.

There are aftermarket dash kits for 65/66 that are electronic, expensive, but might do the trick...

You could try and find a metric speedometer. They measure in kilometers per hour. At least it would seem like you are going faster

Thanks.. that was funny.... and I think I am going to look for an aftermarket one.... Didn't Ford have a 180 mph speedometer as an option???

How about a 140mph speedo? They made those, although they be hard to find and you can not have mine. fd
