BBM Xtreme Energy Solid Cam XE290S-10

The BBM Xtreme Energy Solid Cam XE290S-10 from COMP CAMS is a high-performance hydraulic roller camshaft engineered for naturally aspirated small-block engines seeking aggressive, street-performance power delivery. This solid cam design targets enthusiasts and builders who demand increased valve lift, extended duration, and optimized overlap characteristics without the complexity of adjustable valve train systems. Whether you're building a weekend cruiser with serious acceleration or upgrading an existing engine package, this camshaft unlocks additional horsepower and torque across a broader RPM band than stock or mild-profile alternatives.

The solid cam construction eliminates roller lifter deflection and provides direct, consistent valve actuation for repeatable performance and reliability under sustained high-RPM operation. COMP CAMS' XE290S profile delivers measurable increases in valve lift and duration, forcing more fuel and air into the cylinder during intake strokes and extending exhaust purging for better scavenging—both critical factors in maximizing volumetric efficiency. The hydraulic roller design reduces parasitic friction losses compared to flat-tappet designs while maintaining the durability required for street and strip applications. Precision-ground lobes and premium metallurgy ensure consistent cam wear rates and extended service life across thousands of heat cycles.

This camshaft is ideal for small-block Chevrolet and comparable engine families with factory or aftermarket hydraulic roller lifter systems, making it a direct upgrade path for owners seeking bolt-on performance without complete engine disassembly. Installation requires proper valve-spring selection and pushrod length verification to ensure adequate preload and prevent valve float at peak RPM. The XE290S-10 pairs effectively with matching rocker arm ratios, quality ignition systems, and lean carburetor or EFI tuning to realize its full potential. Dyno-verified gains typically range 30–50 horsepower and 35–60 foot-pounds of torque, depending on existing induction and exhaust systems.
