Olds V8 Xtreme Hyd. Cam XE262H-10

The COMP CAMS Olds V8 Xtreme Hyd. Cam XE262H-10 is a high-performance hydraulic flat tappet camshaft engineered for Oldsmobile V8 engines seeking increased horsepower and torque across mid-to-high RPM ranges. This camshaft is designed for enthusiasts and rebuilders who demand reliable valve actuation without the complexity of solid lifter conversions, making it ideal for street performance builds where hydraulic lifter compatibility is essential. The Xtreme Energy line represents COMP CAMS' commitment to delivering measurable performance gains while maintaining engine durability and ease of installation.

Featuring a 262-degree intake duration and 274-degree exhaust duration with a 110-degree lobe separation angle, this camshaft optimizes valve overlap to maximize breathing efficiency and combustion dynamics in the 1200–5600 RPM operating window. The hydraulic flat tappet design uses automatic lifter adjustment to maintain precise valve clearance throughout engine load cycles, eliminating frequent tuning while reducing wear on valve train components. With intake lift rated at 0.475 inches and exhaust lift at 0.480 inches, the XE262H-10 delivers substantive valve displacement that significantly increases cylinder filling and scavenging without requiring custom valve spring packages or extensive machine work, making it a practical choice for street and street-strip applications.

This camshaft is purpose-built for Oldsmobile V8 platforms and installs directly into stock hydraulic lifter bores, requiring no additional machine work or lifter conversion. Builders and engine shops working on classic muscle cars, restorations, or performance rebuilds will find the Olds V8 Xtreme Hyd. Cam XE262H-10 delivers reliable performance gains without sacrificing streetability or cold-start characteristics. Installation should be performed by qualified technicians familiar with V8 engine assembly and proper valve train setup to ensure optimal results and longevity.
