Our new Corvette HEI Tachometer Drive Distributor allows you to maintain your working tachometer while gaining the reliability and performance of GM High Energy Ignition system. This HEI 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.
There are a couple things to consider when upgrading your Corvette's points style distributor to and HEI system. First, your Corvette's original style ignition shielding must be removed due ot the size of the distributor cap. Second, you'll need the HEI coil pigtail to complete installation. Third, 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 340-365 horsepower applications with the taller intake and the larger distributor cap causes fitment issues with original style dual snorkel air cleaners (including the factory 73-74 version). Zip also offers an electronic distributor with a small cap, see Zip # M-4133 to solve these fitment issues.
