Cam Sync Kit - BBC w/ +.600/+1.000 Raised Cam

The Holley Cam Sync Kit for Big Block Chevy with +0.600/+1.000 raised cam is a precision engine management component designed to integrate advanced cam position sensing into fuel-injected performance builds. This kit delivers accurate camshaft timing feedback to Holley EFI systems, enabling precise fuel and ignition curve optimization across the entire RPM range. The flying magnet sensor design and included target bracket provide reliable signal generation even in high-heat, high-vibration engine compartments typical of carbureted-to-EFI conversion projects.

The kit features a 12mm x 1.00 thread sensor mount and is purpose-engineered for aftermarket big block Chevy applications running elevated cam profiles. The +0.600 to +1.000 inch camshaft height specification indicates compatibility with aggressive solid-roller or hydraulic roller cams commonly found in high-output street and competition engines. By providing real-time cam phasing data to the Holley EFI controller, this sensor enables tune optimization for peak torque delivery, improved throttle response, and refined cold-start characteristics—critical factors in fuel-injected big block platforms where stock cam timing references no longer apply.

This cam sync kit is essential for builders converting carbureted big block Chevy engines to Holley EFI systems or tuning existing fuel-injected builds with non-stock cam profiles. It suits restoration projects, performance street builds, and race applications where ECU-driven fuel mapping depends on accurate valve event feedback. The compact footprint and straightforward installation integrate seamlessly into custom engine bay layouts without requiring extensive fabrication or rewiring of the main EFI harness.

Holley's cam position sensing technology is widely adopted in the performance engine management aftermarket, trusted by engine builders and tuners who demand reliable sensor data for complex multi-cylinder calibration. This kit represents a direct OEM Holley product—not a third-party sensor adaptation—ensuring compatibility with Holley's native EFI software and sensor signal conditioning without adapter complications or tuning workarounds.
