A small block Ford converted to sequential fuel injection needs a cam signal as well as a crank signal, which a standard distributor cannot provide. This unit houses dual Hall Effect sensors and a QPQ coated billet shutter wheel on a shaft guided by a sealed ball bearing, so both signals come from one accurate, noise-immune source.

MSD 23773 Dual Sync EFI Distributor Features:

• Dual Hall Effect sensors supply crank and cam signals for sequential EFI.
• Fits Ford 289 and 302 small block engines.
• Shutter wheel is pinned and welded to the shaft for reliability at extreme rpm.
• CNC machined billet aluminum housing, black anodized.
• Race proven steel melonized QPQ coated gear.
• Integrated LEDs allow easy setup, and a blank cap is available for coil-on-plug builds.
• When used with Sniper EFI, ignition adapter PN 558-493 is required.
