BBC Crank and Cam Sensor Kit for EFI

GEN4 Big Block Chevy Cam & Crank Sensor System

Modern Ignition Control for EFI Conversion

Switching to EFI? Good. You need to have precise ignition.

This system brings modern cam and crank signal control to your converted Big Block Chevy—giving you the timing accuracy, stability, and reliability that distributors simply can’t match.

No more timing scatter. No more mechanical limitations.
Just clean, precise ignition control from idle to wide open throttle.

Built for EFI Performance Builds

Traditional distributor setups are one of the biggest weak points in a high-performance BBC:

• Timing drift at high RPM
• Rotor phasing issues
• Mechanical wear and inconsistency

This system eliminates all of that.

At its core is a precision-machined billet aluminum timing cover that mounts both cam and crank sensors in a fixed, rigid position—ensuring accurate signal delivery at all times.

Paired with a custom billet steel cam gear, the system provides reliable cam sync while maintaining durability under extreme load.

Using proven Low Dollar Motorsports sensors and an included MSD oil pump drive, this setup completely replaces the distributor—cleaning up your engine bay and removing a major failure point.

Why This Matters for EFI

With this system, you get:

• Crank-triggered timing accuracy
• Stable spark control at high RPM
• Improved consistency pass after pass
• Better response under load and throttle transitions

Pair it with almost any Holley ECU system, and you unlock true modern performance.
