SBC Cam K-Kit XE274H

The SBC Cam K-Kit XE274H from COMP CAMS is a complete camshaft kit engineered for small block Chevrolet engines seeking aggressive yet streetable performance. This Xtreme Energy hydraulic flat tappet system delivers the mechanical advantage needed for weekend warriors and engine builders who want genuine power gains without sacrificing daily drivability. The kit addresses a critical need: providing a proven, bolt-on solution that includes all essential components—camshaft, lifters, springs, and timing set—eliminating guesswork and compatibility issues during installation.

At the heart of this kit lies a hydraulic flat tappet camshaft with 0.487-inch intake lift and 0.490-inch exhaust lift, paired with a 274-degree intake and 286-degree exhaust duration specification. The 110-degree lobe separation angle optimizes cylinder charging and scavenging for peak performance across the 1800 to 6000 RPM operating range. COMP CAMS engineered the valve springs and lifters to work harmoniously with this aggressive profile, ensuring valve train stability and longevity. The included timing set guarantees precise cam timing synchronization, critical for maximizing fuel efficiency and power delivery. Hydraulic flat tappet design eliminates the need for frequent valve adjustments while providing reliable valve train geometry.

Small block Chevy enthusiasts—from street rod builders to performance restoration shops—rely on this kit for engines running carbureted or early fuel injection systems where aggressive cam profiles deliver tangible results. The 1800 RPM low-end torque floor makes this ideal for street applications without excessive idle quality sacrifice, while the 6000 RPM power band ceiling suits most naturally aspirated small block builds. Installation requires proper synchronization with your timing chain and attention to oil capacity, as the increased valve lift demands adequate lubrication. This kit is compatible with standard small block Chevy blocks (262, 283, 305, 327, 350, 400 displacements) and works with both original and aftermarket cylinder heads supporting flat tappet lifter geometry.
