Chevelle Electronic Ignition - New Spark

Update Your Ignition The Easy And Affordable Way

By Jason Walker, Photography by Cindy Walker

To back up any type of power-adding parts, such as the Holley intake and carburetor swap done to the '67 Chevelle Wagon shown in this issue, you almost can't get away without updating the ignition system, as well. If you are adding more fuel and air, then you're going to need more spark. Besides, your stock-style points, coil, etc., may not be able to keep up with the new demand for more spark causing loss of power, fuel economy, and overall driveability, which then would defeat the purpose of maximizing performance with the other bolt-ons.

Pertronix has engineered some serious advances in the technology behind electronic ignitions. No longer do we have to mount bulky boxes on the firewall containing the necessary electronics to not only run the ignition, but also create that wonderful buzzing that travels through the car stereo. With the leaps forward in the size of computer chips, Pertronix is able to place all necessary electronics inside a molded epoxy unit small enough to fit inside the distributor.

Knowing all about the convenient size of the unit, the only question left was how easy it is to install and wire. In fact, we were told this conversion was easier and less time-consuming than changing the factory points, condenser, cap, and rotor. Not only was the conversion that easy, but now we'll never have to change the points and condenser again. With all that out of the way, we checked the price of the kit; we were even more interested in showcasing the Ignitor II in our low-buck performance issue. In fact, we had the perfect "guinea pig" on which try out the Ignitor II, our '67 Chevelle Wagon-not just because we are in the process of updating the car with many low-buck performance parts, but more because the Wagon is a daily driven freeway commuter. Not only will the Ignitor II see an enormous amount of driving time, but it will also see the demands of sitting in traffic for long periods of time at an idle.

While that test may take some time for any definitive answers, fuel mileage and throttle response are immediate improvements. The Wagon's gas mileage with the stock two-barrel carburetor and points-type ignition averaged 12-14 mpg during freeway commuter traffic. Now with the Holley intake/Street Avenger carb and the Pertronix Ignitor II, 40,000-volt Flame-Thrower coil, and wires the mileage jumped to 15-17 mpg. With this type of improvement and the inexpensive cost of these relatively easy-to-install performance parts, they will pay for themselves every time the your fuel tank is filled (providing the throttle isn't slammed to the floor at every stop light) and at every normal tune-up by only eeding a replacement of the distributor cap and rotor.

Check out exactly how easy it was to install the Pertronix Ignitor II, and keep in mind that not only will it improve any car with points-type ignition with regards to fuel mileage and throttle response, but it is also completely hidden inside the distributor for the discreet minded and produces no feedback through the car stereo.
