SBC Xtreme Hyd. Roller Cam XR270HR-10

The SBC Xtreme Hyd. Roller Cam XR270HR-10 from COMP CAMS is a high-performance hydraulic roller camshaft engineered for small-block Chevy engines seeking aggressive mid-range power and reliability. This camshaft is purpose-built for street performance and light competition applications where consistent valve timing and reduced maintenance are priorities. Hydraulic roller designs eliminate the need for frequent valve lash adjustments, making this cam ideal for enthusiasts who demand both performance and dependability without constant tuning.

The XR270HR-10 delivers 0.495-inch intake lift and 0.502-inch exhaust lift across a 270-degree intake and 276-degree exhaust duration window, with a 110-degree lobe separation angle that promotes smooth power delivery and street-friendly characteristics. The hydraulic roller design minimizes friction losses and wear on valve train components, while the specified 1600 to 5400 RPM operating range ensures broad torque development ideal for daily-driven performance vehicles. COMP CAMS' Xtreme Energy profile maximizes efficiency throughout the rev range, allowing smaller displacement engines to achieve meaningful horsepower gains without sacrificing drivability or engine longevity.

This camshaft suits small-block Chevy platforms from 262 to 400 cubic inches and pairs well with stock or mildly modified cylinder heads and intake systems. Installation requires proper valve train geometry verification and rocker arm ratio confirmation to ensure accurate valve lift at the valve seat. Professional installation is recommended to verify timing, clearance, and baseline engine tune, ensuring maximum performance and protection of internal engine components.
