Camshaft CRB XE256H-10

The Camshaft CRB XE256H-10 from COMP CAMS is the upgrade serious engine builders reach for when seeking measurable gains in mid-range torque and responsive power delivery. Whether you're tuning a street engine, weekend warrior build, or performance project, this hydraulic roller camshaft delivers the valve timing geometry that transforms stock cylinder head potential into real-world horsepower. Built for enthusiasts who demand both reliability and noticeable performance improvement without requiring exotic fuel or extreme RPM limits.

The XE256H-10 profile utilizes COMP CAMS' proven roller lifter technology to reduce parasitic friction losses while extending component life compared to flat-tappet designs. The hydraulic roller design automatically compensates for valve train wear and thermal expansion, eliminating lash adjustment headaches and ensuring consistent valve events across the entire RPM band. The specific grind geometry creates optimized intake and exhaust valve overlap characteristics that boost scavenging efficiency and improve volumetric efficiency in the 2,000–6,500 RPM range where real driving happens.

This camshaft is engineered for small-block applications and pairs seamlessly with stock or mildly ported heads, making it ideal for carbureted and fuel-injected engines alike. Installation requires the use of hydraulic roller lifters and compatible timing components, so verify your engine platform and lifter type before ordering. Proper valve lash setup and timing set are essential for peak performance; consult your engine builder or COMP CAMS' detailed specifications sheet to confirm compatibility with your specific block, head, and induction system. Weighing 10.14 lbs, this precision-engineered component belongs in any well-planned performance package.
