Racing Distributor SBC Locked Out Advance

The Performance Distributors Racing Distributor SBC Locked Out Advance is a magnetic pickup distributor purpose-built for small block Chevy high-performance and racing applications where ignition timing control demands precision and reliability. Designed with a locked advance mechanism and HEI-style terminal, this black distributor eliminates mechanical advance variables that can compromise consistency during aggressive acceleration and high-RPM operation—a critical requirement in race environments where split-second timing stability directly impacts power delivery and throttle response.

The locked advance feature removes the centrifugal weights that traditional distributors use to automatically increase timing as engine speed climbs, giving tuners complete manual control over ignition advance curve through external timing adjustment alone. This approach is standard in competition engines where baseline timing, fuel octane rating, and boost levels are optimized as a complete system. The magnetic pickup design delivers clean, noise-free signal to ignition controllers and aftermarket management systems, supporting both carbureted and fuel-injected small block platforms. The HEI-style terminal accommodates standard coil packs and late-model ignition wiring configurations common in street and strip applications.

This distributor suits small block Chevy engines in circle track, drag racing, road course, and high-output street applications where consistent ignition timing and simplified tuning are priorities. It pairs effectively with programmable ignition systems and serves as a foundation component in builds emphasizing reliability and repeatability over factory-style automatic advance characteristics.

Performance Distributors has established itself as a supplier of aftermarket ignition hardware for high-output domestic engines, with locked advance and fixed-timing distributors widely adopted in racing shops where control and consistency take precedence over street convenience features.
