Sniper EFI Hyperspark Distributor SBM 318-360

The Holley Sniper EFI Hyperspark Distributor (part number 565-304) is a Hall Effect equipped ignition distributor purpose-built for small block Mopar 318–360 engines running Holley Sniper EFI fuel injection systems. This polished aluminum unit combines OEM-style HEI terminal compatibility with modern sensor technology, delivering precise timing control essential for fuel-injected performance and street applications.

The Hall Effect pickup design provides superior trigger stability compared to older magnetic pickup systems, ensuring consistent ignition timing across varying engine speeds and loads. The HEI-style terminal accepts standard plug wire sets, simplifying installation into existing wiring harnesses. Polished aluminum construction offers both durability and a finished appearance suitable for visible engine bay mounting. The distributor integrates with Sniper EFI's closed-loop ignition mapping, allowing real-time timing adjustments based on engine knock, fuel quality, and operating conditions—capabilities unavailable with traditional mechanical or points-style distributors.

This distributor is engineered for Mopar engine builders and street machine enthusiasts converting 318–360 cubic-inch engines to Sniper EFI fuel injection. It addresses a critical gap: factory Mopar distributors lack the sensor output required by modern EFI systems, while generic aftermarket distributors do not account for Mopar's unique bolt pattern and timing mark positions. Applications range from classic muscle car restorations to high-performance street engines where repeatable cold-start performance and load-dependent timing curves are non-negotiable. The kit format ensures correct calibration out of the box.
