The SBC XFI Hyd Roller Cam 280XFI HR13 by COMP CAMS is a performance hydraulic roller camshaft engineered for small-block Chevrolet engines running Holley's XFI fuel injection system. This cam is purpose-built for builders and enthusiasts seeking seamless integration between traditional hydraulic actuation and modern EFI management, eliminating the tuning compromises that plague carburetor-to-injection conversions. Whether you're resurrecting a classic engine with contemporary fuel delivery or building a new small-block package, this roller cam delivers the mechanical reliability of hydro lifters combined with the precision control that electronic fuel injection demands.
Built with COMP CAMS' proven roller cam profile, the 280XFI HR13 features precision-ground lobes optimized for the 280 cubic-inch displacement range and XFI's closed-loop fuel and ignition algorithms. Hydraulic roller lifters absorb valve train shock while maintaining consistent lash control, extending component life and reducing noise—critical advantages when paired with modern ECU feedback that continuously compensates for ignition and fuel mixture. The roller design minimizes friction losses compared to flat-tappet alternatives, freeing more horsepower for the dyno while ensuring EFI sensors read clean, stable combustion events. This specification is tailored for street and strip applications where reliability and repeatability trump raw max-lift aggression.
Installation suits any small-block Chevy engine with XFI conversion intent: 350, 327, or displacement-matched builds. Proper lifter preload and timing set are non-negotiable; your EFI tuner must validate cam synchronization after installation to ensure the crank trigger and fuel injector pulse align. Most builders pair this cam with quality roller lifter sets, a rigid timing cover, and verified fuel rail pressure regulation to maximize the XFI system's compensation window. The 9.54 lb weight is consistent with stock-replacement roller cam mass, simplifying engine balance calculations and accessory drive compatibility.
