Description
If you're running a carbureted GM HEI distributor setup and want predictable, consistent ignition timing during high-RPM pulls, you need vacuum advance lockout control. This Proform plate eliminates unwanted vacuum advance fluctuations that can cause detonation, timing scatter, or performance loss under boost or aggressive throttle conditions. Lock in your base timing and keep it there—critical for serious street and strip applications.
