The speedometer runs off a gear in the transmission. There are different
gears for different rear end ratios. I don't know much about them, other
than that they can be swapped out with the trans in the car. There may
be something in the 311s pages listing which gear is for which rear end.
This gear will also affect the odometer.
Just to see if the problem is actually in the speedometer, drive at a
steady 60 mph and and clock how long it takes to go a mile as shown on
the odometer. If it takes 60 seconds, the problem is not with the
speedometer
Peace,
