SBC Cam K-Kit XE274H

The SBC Cam K-Kit XE274H from COMP CAMS is a complete camshaft kit designed specifically for small-block Chevrolet engines. This kit is ideal for builders and enthusiasts looking for enhanced performance characteristics, including increased lift, duration, and aggressive valve timing. It is well-suited for street performance builds, racing applications, and serious engine modifications.

The XE274H profile is engineered to unlock horsepower and torque across mid to high RPM ranges while maintaining a street-friendly idle. This kit includes precision-ground cam lobes made from proprietary materials that resist wear and deformation during high-RPM operation. The K-Kit format ensures that all components, including the camshaft, lifters, pushrods, and valve springs, are calibrated to work together seamlessly.

SBC owners with 350, 400, or 327-cubic-inch displacement engines will benefit most from this cam kit, whether in naturally aspirated or moderately boosted configurations. The aggressive lobe separation and increased valve overlap enhance cylinder scavenging and fuel mixture charge, leading to significant gains in peak horsepower. Proper installation requires consultation on the valve train, particularly regarding pushrod length.
