COMP Cams Camshaft CS XE250H-10

The COMP Cams Xtreme Energy camshaft, grind number XE250H-10, features a 206-degree intake and 212-degree exhaust duration at 0.050 lift. This design is intended to bridge the gap between mild street cams and aggressive race cams, aiming for improved torque and responsiveness without sacrificing too much drivability. It's built for Chevrolet Small Block engines, specifically those with a 4.040" bore and 3.480" stroke, like a 356ci displacement, and works best with a 9.25:1 compression ratio.

This camshaft is designed to provide strong torque output, with a peak of 417 ft-lbs at 3700 RPM in a 356ci engine setup, while also aiming for excellent fuel mileage and a smooth idle. The quicker opening lobe profiles contribute to increased responsiveness and a broader powerband. It's a popular choice for street applications that also see regular use, offering the durability needed for daily driving. For optimal performance, it's recommended to pair this camshaft with COMP Cams roller rockers and matched valve springs, along with other performance upgrades like an aftermarket intake manifold and headers.

This camshaft fits a wide range of Chevrolet GEN 1 Small Block engines, including popular displacements like the 350, 305, and 400 cubic inches. It's important to note that it is not compatible with factory roller camshaft engines from 1985 and newer, or LS-based engines. Always confirm your engine's camshaft type before installation.
