Probably not with the stock differential ratio.

Quickest thing to check may be the speedo, if you can find a measured mile
marked on any of the roads in your area. (There used to be a lot of
"spedometer check" zones on major highways, but I haven't seen one in a
long time.) Just time how long it takes to cover a known mile at a constant
speed, then do the math. It should take exactly a minute at 60MPH, or two
minutes at 30. I'll leave any more complicated calculations up to you.
If your speedo's correct, that leaves the tach.
