Speedway Motors 28799601 Details

Adjusts GM points style distributors for any driving condition. Includes allen wrench and instructions. Easy to install.

Springs & cam plate not included (use 550-929 if needed).

  • 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
  • Includes 3/32" Allen wrench and easy-to-follow instructions

A standard component to adjust ignition timing but this application is for distributors pretty much last manufactured in 1974 and are now obsolete except, I am using one. It was back ordered and the product personal called me to insure that I would indeed be able to get one and they called me again when the back order was completed. You can not ask for better customer service than that.
