COMP Cams Camshaft CS 47S 297Hxl R7 Ope

This COMP Cams OWM T/C Series camshaft, part number 12-843-14, is a solid roller camshaft designed for Small Block Chevrolet (SBC) engines. It's built for open wheel modified racers looking for an edge, offering a broad torque curve with improved power and reduced tire spin. This camshaft is specifically engineered for racing applications, requiring a good intake manifold and cylinder heads, and is intended for engines with 383+ cubic inches and a compression ratio of 12:1 or higher, running on gasoline or alcohol fuel.

The OWM T/C Series camshafts feature a 4/7 firing order swap, which is a key design element for open wheel modified racing. This configuration helps manage tire spin by providing a more predictable torque delivery, allowing the chassis to hook up effectively without running out of horsepower at higher RPMs. COMP Cams has developed these cams with advanced lobe designs to balance gentle torque for initial traction with strong top-end power. They are intended to be used with Race Series valve springs and Endure-X Solid Roller lifters for optimal performance and durability.

This camshaft is not legal for IMCA racing and is not CARB approved, meaning it cannot be shipped to California. For 1955-1957 Chevrolet engines, a specific oiling groove is required on the rear journal; this particular part number does not include that groove, so please contact us if your application requires it. This camshaft fits a wide range of Chevrolet GEN 1 Small Blocks, but it does not fit LT1/LT4 engines or factory roller Small Blocks from 1985 and newer. Always confirm your engine's configuration before installation.
