The Dragon Fire 1962-1974 Corvette HEI Tachometer Drive Distributor allows you to maintain your working tachometer while gaining the reliability and performance of the GM style 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 to 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. Lastly, you'll need to change the spark plug wires to include the HEI style female distributor connection. Zip offers multiple universal wire sets that include both male and female distributor terminal boots. See related items for wire sets with standard or ceramic boots, 90 degree angle or straight options depending on application needs.

See Zip # M-3709 for the Red Cap version of the HEI tach drive distributor.

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 1973-1974 version). Zip also offers an electronic distributor with a small cap, see Zip # M-4311 or M-4312 to solve these fitment issues.
