MSD 23451 Pro-Billet Chevy Cam Sync Distributor Hall Effect Large Cap

The MSD 23451 Pro-Billet Cam Sync Distributor is purpose-built for Chevy V8 engines running aftermarket electronic fuel injection systems that require a cam synchronization signal. Many sequential EFI systems fire fuel injectors in the same order as the engine's firing order and need a sync signal to identify when cylinder number one is firing — this distributor delivers exactly that with precision.

Equipped with a Hall-Effect sync pickup, the MSD 23451 provides a clean, reliable signal to the ECU. A built-in LED indicator illuminates when the sync signal is detected, simplifying initial setup and diagnostics. The adjustable cam sync pickup can be set to your ECU's specific requirements, with adjustment range up to 60° BTDC.

Key Features:

• Hall-Effect sync pickup for reliable EFI cam synchronization signal
• Built-in LED signal indicator lights up when sync signal is active for easy setup
• Adjustable cam sync pickup — configurable up to 60° BTDC to match ECU requirements
• Adjustable slip collar for accurate installation depth compensation in engines with modified deck heights or custom intake manifolds
• Adjustable race rotor for precise rotor phasing
• Iron/steel gear for durability
• Large cap design for improved wire routing and clearance
• Includes: distributor cap, adjustable race rotor, LED signal indicator, magnetic pickup, and Hall-Effect pickup
• Must be used with an MSD 6, 7, or 8-series ignition
