Simple Upgrade Gains More Power.
Stock HEI distributors are like you-know-what. Everybody’s got one. Stock HEIs generally work well in stock applications, and for the guy who doesn’t plan on running his motor much past 5,000 rpm, they’re perfectly fine. However, for those looking to have some fun with spirited driving, stock just won’t do.
Fortunately for HEI users, Pertronix Performance Products offers an HEI ignition upgrade for only $119.95. It comes with everything you need for the ultimate HEI tune-up. In every kit you’ll find an adjustable vacuum-advance canister ranging from lockout to 22 degrees of advance, a new module with wiring harness and capacitor, a selection of high-performance advance springs, and a new weight kit. Also included is the Pertronix patented coil that develops 67 percent more energy over the OEM units. This means forcing your back into your seat with misfire-free performance up to a minimum of 7,500 rpm. And for underhood details, Pertronix has red, blue, or black caps with solid brass terminals and rotor. It may not be the billet distributor you’ve been drooling over (although Pertronix has those too), but the cost is substantially lower, and a better HEI system like this can allow wider plug gaps, which leads to larger sparks, and ultimately more power!
