Brand new reproduction Tic Tock Tach designed to replace the old broken tachometer. This tachometer has the clock in the center of the gauge. This is a three bols design. Sold individually. This is just the Tick Tock Tach for A 1970-72 442, W-30, W-31, Rally 350 & Hurst/Olds. If you're looking to installing a factory tachometer, This Is For You. Tachometers Have Electronic Movement. Tachometers will work with factory GM points or factory HEI ignition. When using an aftermarket ignition system likes MSD, Accel, Patronix, ect. A lot of these systems generates higher output voltage to the tach lead than what a factory GM tach can handle. Factory GM tachs can operate on voltage ranging from 11.2 to 14.7 Most aftermarket ignition systems generate over 18 volts. You will need to buy from the manufacture of your ignition system an adapter to lower the voltage to the GM factory voltage.
