Adjustable Vacuum Advance Kit
Fits: 1975-'81 GM HEI Distributors
Description
- Allows you to change the amount of ignition vacuum advance for maximum part-throttle performance while preventing 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
- Perfect companion to Moroso HEI Advance Curve Kit No. 72300
