COMP Cams Camshaft CS 47S 288R-6

This is the COMP Cams CS 47S 288R-6 solid roller camshaft, designed for Chevrolet Gen 1 Small Block engines. It's a popular choice for drag racing and oval track builds, especially for those looking to maximize torque and power in heavy cars or smaller displacement engines on short tracks. This camshaft is engineered to work with higher compression ratios and higher stall speed torque converters, making it suitable for demanding performance applications.

The CS 47S 288R-6 features a 4/7 cylinder firing order swap, which helps to reduce crankshaft flex and improve overall engine balance at high RPMs. This design contributes to a smoother running engine and can allow for higher revs. It's best suited for engines in the 355-400 cubic inch range, particularly when paired with a 4-barrel carburetor and a torque converter with a stall speed of 4000 RPM or higher for optimal performance. For even higher RPM use on longer tracks, a 5000+ stall converter and 11:1+ compression are recommended to take full advantage of its mid and top-end power characteristics.

It's important to note that this camshaft is intended for engines with flat tappet camshafts. It will not fit factory roller Small Blocks from 1985 and newer, nor will it fit LT1, LT4, or LS-based engines. Additionally, 1955-1957 Chevrolet 265 engines require a specific oiling groove on the rear journal, which this particular camshaft does not have. Always confirm your engine's configuration before ordering to ensure proper fitment.
