XFI Hyd. Roller Cam - 5.7L Hemi XFI273H14

The COMP CAMS XFI Hydraulic Roller Cam for 5.7L Hemi XFI273H14 is a performance camshaft engineered for Gen III Hemi engine platforms seeking enhanced power delivery with modern reliability. This hydraulic roller cam combines aggressive valve lift and duration with the low-maintenance characteristics of hydraulic roller technology, making it the preferred choice for street performance and light competition builds where valve train durability and consistent operation matter.

The XFI273H14 specification delivers 0.547 inch intake lift and 0.550 inch exhaust lift across a 273 degree intake and 277 degree exhaust duration window at 0.050 inch tappet clearance. The 114-degree lobe separation angle (LSA) preserves streetable idle quality while the 2000–6200 RPM power band targets mid-range torque production typical of naturally aspirated Hemi applications. Hydraulic roller followers eliminate the wear patterns associated with flat-tappet designs, reducing maintenance intervals and enhancing longevity in daily-driven and high-mileage scenarios.

This camshaft suits Mopar Gen III Hemi engines across 5.7L displacement applications, including vehicles originally equipped with stock cam profiles where additional cylinder head breathing is desired without requiring extensive head or intake modifications. The moderate lift and duration curve remains compatible with factory valve springs and pushrods in most stock and mildly modified engine configurations, reducing the need for supplementary valvetrain upgrades.

COMP CAMS camshafts are manufactured to strict OEM tolerances and grind specifications, ensuring proper clearances with factory lifter bores and rocker geometry. Installation requires standard camshaft timing techniques and verification of valve-to-piston clearance in modified applications. Consult engine build documentation to confirm compatibility with your specific Hemi platform and supporting valvetrain components.
