Speedo and tach won't keep up?

So, inconsistantly my speedo and take will sometimes "hang" at a specific RPM and speed during hard acceleration, then catch back up a moment later. The car pulls smooth, so it's not like it's hit a wall at that point. This doesn't happen all the time just every once in a while.

Has anyone heard of this before or have any idea what might be going on? Really could use some advanced tech assistance here.

Probably a good idea to tell us the specifics of the car - year, engine trans, mods, etc. - , then post this in "General 67-02 F-Body Tech". As noted in the stickies, this forum is basically dead.
