Our new Corvette HEI Tachometer Drive Distributor allows you to maintain your working tachometer while gaining the reliability and performance of HEI. This high energy ignition distributor comes with a 65,000 high performance mega coil, an adjustable vacuum advance canister for better performance advance curve, high quality bronze bushing for reduced friction and extended life, a corrosion resistant shaft that reduces friction and provides concentric operation, a heavy duty gear that is ground to exact tolerances, a heavy duty coil to produce an increased spark to light the fuel mixture for high performance, high quality brass terminals for maximum high voltage transfer, precision advance weights and center plate that eliminate erratic timing, and a lifetime warranty.
A couple things to consider when upgrading your Corvettes points to HEI are that you must remove your Corvettes ignition shielding due to the distributor cap size and Zip's Corvette HEI coil pigtail is a must have to complete installation. To install the new HEI distributor you must remove the ballast resistor (on equipped Corvettes) or white cloth covered wire which drops voltage to your original points style distributor. Voltage for HEI distributors should be 13.7 volts (approximately, when vehicle is running) to operate at peak efficiency.
Note: This HEI tachometer drive distributor will work on all 1962-1974 Corvettes except 340 horsepower applications.
