Product Details

This is the COMP Cams CS 311Qs10 .900 Base hydraulic roller camshaft, designed for highly modified 420+ cubic inch stroker applications using OE roller Small Block Chevrolet engines. It features a 4-pattern lobe design with intake duration of 258 degrees and exhaust duration of 260 degrees at .050 lift, and .900 inch base circle. This camshaft is recommended for builds with higher compression ratios and requires a 3500+ RPM stall torque converter to perform optimally.

This camshaft is built for serious performance upgrades. The 4-pattern lobe design helps optimize valve events across the RPM range, contributing to improved power delivery in demanding applications. Its .900 inch base circle is a key specification for compatibility with certain OE roller lifter setups and allows for more aggressive lobe profiles. COMP Cams is a well-known name in performance engine building, and this camshaft is a solid option for those looking to extract significant power from their modified Small Block Chevy.

When installing this camshaft, ensure you have the necessary supporting modifications, including a high-stall torque converter and potentially upgraded valve springs to match the cam's lift and duration. It's also crucial to verify that your engine's valvetrain is compatible with the .900 inch base circle. This camshaft fits a wide range of 1987 and newer Small Block Chevrolet engines with factory roller camshafts, including popular models like the Chevrolet Camaro, Corvette, and C/K series trucks.
