COMP Cams Camshaft CB Nx 294H-13

This COMP Cams CB Nx 294H-13 camshaft is a performance upgrade for Chevrolet Big Block engines, specifically the 396 to 454 cubic inch displacements. It's designed for race-only applications and is intended to be used with multi-stage kits, an 871 blower, and requires supporting modifications like good cylinder heads, an upgraded intake manifold, appropriate gearing, and a torque converter with a 3500+ stall speed. This camshaft features a 250-degree intake duration and 264-degree exhaust duration at 0.050 inch lift, with a 113-degree lobe separation angle, making it suitable for high-RPM power bands.

The 294H-13 camshaft is built with a hydraulic flat tappet design, offering a balance between performance and the reliability of hydraulic lifters. COMP Cams is a well-known name in performance engine building, and this camshaft is part of their Nitrous HP line, indicating its focus on maximizing power output for competitive use. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Additionally, it is intended for engines originally equipped with flat tappet camshafts, and specific early BBC models (1965-66 396 with an oiling groove in the rear journal) require a different part number.

When installing this camshaft, ensure your engine's valvetrain components, including cylinder heads, intake, and rear gearing, are up to the task. A proper break-in procedure is crucial for hydraulic flat tappet camshafts to prevent premature wear. This camshaft is a solid option for builders looking to extract maximum performance from their Big Block Chevrolet for track or competition use.
