As long as you have stock sized tires, it should be normal.

get a friend and mark the rear tire on the outside and have some one under the car to look at the yoke. spin the tire a full 360 and have the person under the car count the revalution of the yoke so the yoke should spin 3.23 times to the one tire revalution....and that 3.23:1. and tires will

Seems close to what my 3.23's were at 70mph. Is your tach accurate? I know some of them read 100-200rpms higher.
