This Chevy V8 EFI Dual Sync distributor is designed for precise engine control, featuring a Hall Effect magnetic trigger and melonized iron gear for compatibility with factory roller cams. It includes a black male/HEI-style distributor cap and an internal ignition module, eliminating the need for an external ignition box. The unit supports both vacuum and mechanical advance for versatile tuning, while the natural-finish aluminum housing ensures durability. With no slip collar or mechanical tach drive, it’s tailored for EFI setups rather than marine applications, offering reliable synchronization for modern fuel-injected V8 engines.
