1962-1974 Dragon Fire HEI Distributor w/Tach Drive (Red Cap)

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 of things to consider when upgrading your Corvette's points-style distributor to a HEI system. First, your Corvette's original-style ignition shield must be removed due to the size of the distributor cap. Second, you'll need the HEI coil pigtail to complete the installation. Third, to install the new HEI distributor, you must remove the ballast resistor (on equipped Corvettes) or the white cloth-covered wire that drops voltage to your original points-style distributor. Voltage for HEI distributors should be 13.7 volts (approximately) when the 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, in 90-degree or straight configurations, depending on application needs.

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), which cause fitment issues with original-style dual snorkel air cleaners (including the factory 1973-1974 version).
