Dual Sync Distributor SBC/BBC

The Dual Sync Distributor SBC/BBC from HOLLEY is an essential upgrade for small-block and big-block Chevrolet engines that demand reliable spark timing control. This distributor is designed for street machines, race applications, and high-performance restorations, providing superior performance where traditional distributors may falter under load and RPM variations.

Featuring dual synchronization technology, this distributor ensures consistent ignition events across the entire operating range, effectively eliminating timing scatter that can lead to hesitation, detonation, and power loss. Its internal design integrates centrifugal advance weights and vacuum signals, maintaining precise spark delivery without the timing drift associated with older single-sync units.

Ideal for builders looking for plug-and-play spark timing control, this distributor is compatible with both carbureted and fuel-injected engines. Its robust construction and sealed design withstand the rigors of high-RPM operation and aggressive throttle transitions, making it a reliable choice for performance enthusiasts.
