Hi Dwright,
F.Y.I. I took my 82 up on the highway today, At 75 mph, the tach was showing 1800 rpm. I don't think that there is anything wrong with your tach.
Take care,
Tom

Vette(s): 1978 vette with an 80-82 stlye rear end molded in. BW six speed & an L82... for now. Lowered with VBP springs and bilsteins. Polished torq thrust wheels. New paint, audio system, aluminum radiator... Flowmaster and extreme flow exhaust components.
With a 27 inch tall tire, (255/60r15) a .7 overdirve (I think it's .7), a 2.87 diff ratio, at 75 mph you should be at 1875 RPM. Click the link to see for yourself http://richmondgear.com/streetcalculators.html-Adam
