Hyperspark Distributor EFI Small Cap SBC/BBC

The Holley Hyperspark Distributor EFI Small Cap SBC/BBC is a modern electronic fuel injection distributor engineered for small block and big block Chevrolet engines seeking reliable spark timing control without the complexity of traditional carbureted systems. This Hall Effect-equipped distributor replaces outdated mechanical distributors while maintaining compatibility with classic engine platforms, making it ideal for hot rodders, engine builders, and restoration enthusiasts upgrading to EFI technology.

Built with Holley's proven Hall Effect pickup sensor, the Hyperspark Distributor EFI delivers precise ignition timing through digital signal processing, eliminating mechanical wear points and inconsistencies found in points-and-plugs designs. The HEI-style terminal configuration ensures straightforward wiring integration while the black finish resists corrosion in engine bay environments. Advanced curve-mapping electronics automatically adjust timing across the RPM range, optimizing combustion efficiency and fuel economy while reducing emissions—critical for both street and competition applications requiring adaptive ignition control.

Engine builders upgrading SBC or BBC platforms to Sniper EFI fuel injection systems will find this distributor essential for complete ignition system integration. The small cap design fits standard Chevrolet engine bay dimensions while the compact 6.8 x 6.5-inch footprint minimizes installation interference. Whether building a restomod, race engine, or modern performance upgrade, this Holley unit works seamlessly with EFI manifolds and ECU tuning software to deliver repeatable, programmable ignition timing across all load and throttle conditions.
