COMP Cams Camshaft CS 47S XE274H-10

This COMP Cams XE274H-10 camshaft is designed for Chevrolet Small Block engines from 1958 through 2002, specifically those using hydraulic flat tappet lifters. It's a popular choice when you're looking to improve your engine's mid-range torque and throttle response, making it feel much more lively when you're accelerating from around 2500 RPM and up. This camshaft is a solid option for street performance builds where you want a noticeable boost in power without going to an extreme setup.

The XE274H-10 features a 4/7 swap firing order, which can help reduce crankshaft stress and improve exhaust scavenging, leading to that improved mid-range performance. It's built with a hydraulic flat tappet design, meaning it's compatible with many older Chevy Small Block engines and doesn't require special roller lifters or blocks, though it does call for a 2500+ stall speed torque converter if you're running an automatic transmission. The camshaft itself is well-built, designed to handle the demands of regular driving while providing that extra kick when you need it.

When installing this camshaft, remember to check your specific engine's configuration. While this cam is intended for flat tappet blocks, some later model engines (1985 and newer) came with provisions for roller cams. It's always a good idea to confirm your block type by removing the intake or timing cover before installation. This camshaft is not CARB approved and cannot be shipped to California.
