Info

Super-tune your HEI ignition with this analog tuning kit from Speedway Motors. Improve power, acceleration, and economy, while learning how to get the most out of your engine...the old fashioned way. You don't need expensive ignition boxes or ugly coil-on-plug ignitions to build a fun, responsive engine (just ask Mickey, Smokey and Grumpy...the mechanics, not the dwarfs).

All HEI distributors are shipped with a “base” tune designed to get you up and running. The “base” tune is for an average combination, resulting in average performance. Our DIY super-tuning kit helps you optimize your ignition advance at all engine speeds.

The adjustable vacuum advance dials in more ignition advance for good part-throttle performance, while preventing the harmful effects of spark knock (detonation) under high loads. The centrifugal weight set offers numerous advance curves to increase spark lead as RPM increases. Fits GM-style HEI distributors (large-cap HEI).

Adjustable Vacuum Advance Kit, GM HEI Distributor

Adjust your GM HEI distributor for any driving condition. This kit allows you to change the amount of ignition vacuum advance for maximum part-throttle performance while preventing the harmful effects of spark knock (detonation). Dial-in as much spark advance as conditions permit — add more advance under light load conditions to improve throttle response and fuel economy, or limit spark advance in high compression engines and high load conditions to eliminate knock.

  • Built-in stop prevents the adjustment screw from "backing out" like other designs
  • Easy to install
  • Includes 3/32" Allen wrench and easy-to-follow instructions

GM HEI Distributor Mechanical Advance Curve Weight/Spring Kit

Modifies any GM HEI distributor with either clockwise or counterclockwise rotation and offers plenty of curve possibilities.  Center plate eliminates overcentering of centrifugal weights.  Comes complete with detailed instructions.
