Anyone ever run a mechanical tachometer?

I tend to agree with that for the most part, although I have driven a few, one a dragster, that were pretty decent.

Hey, that's why we have "shift lights" today...:D

we had one on the hemi for a while( back in the day) worked great, very accurate, the cable was always a pain in the *** when working on it!
