Description
Eliminating vacuum advance during high-performance driving ensures consistent ignition timing and prevents detonation issues that compromise engine reliability. This lockout is essential for tuned engines running aggressive ignition curves, carbureted setups, or forced induction applications where vacuum-actuated advance creates unpredictable timing variations. If you're serious about repeatability and control, this is a non-negotiable upgrade for your HEI distributor.
