FAST 304013 XDi Race Cam Sync Small Cap Distributor Chrysler RB 426-440

The FAST 304013 XDi Race Cam Sync Distributor is a precision-engineered cam synchronization solution purpose-built for Chrysler RB 426-440 big block engines. Designed as a turnkey alternative for builds that traditionally rely on a crank trigger, this small cap distributor delivers an accurate cam sync signal to aftermarket sequential fuel injection systems — enabling proper individual cylinder spark timing and fuel injector phasing for maximum power and efficiency.

At the heart of the 304013 is a Hall-effect style optical pickup that maintains a steady ±½-degree trigger signal — a significant advantage over inductive-style pickups commonly found in competing units, which are known to drift at high RPM. This precision makes it ideal for race, high-performance street, and marine builds where ignition accuracy is non-negotiable.

Key Features:

• Accurate cam sync signal for aftermarket sequential EFI systems
• Hall-effect optical pickup — steady ±½-degree trigger signal at all RPM
• Billet aluminum housing with precision-ground stainless steel shaft
• Premium bearings and hand-assembled components for consistent shaft end play
• Includes precision-machined bronze gear
• Locked advance — designed for use with a crank trigger and external ignition box
• Small cap design for Chrysler RB 426-440 big block engines
• Suitable for drag racing, high-performance street, and marine applications

The FAST 304013 is sold individually and requires a crank trigger and external ignition box for proper operation. If you're building a serious RB-powered combination with a modern EFI management system, this distributor delivers the signal integrity your setup demands.
