COMP Cams Camshaft CS 266Xos-8

Starting with a 236 degrees of intake duration and 242 degrees of exhaust duration, this COMP Cams CS 266Xos-8 solid flat tappet camshaft is built for Chevrolet Small Block engines, specifically targeting 327-358 cubic inch displacements. It’s designed for tight track applications with a 9:1 compression ratio, paired with a 2-barrel carburetor, iron intake, and exhaust system. This camshaft is a solid option for those looking to enhance the performance of a wide range of classic Chevrolet and GM vehicles, including models like the Chevrolet Camaro, Corvette, and Caprice, as well as various C/K series trucks and S-10 pickups from the 1980s and early 1990s.

This camshaft features a .558-inch intake lift and a .578-inch exhaust lift, contributing to improved airflow and power output. The solid flat tappet design is known for its durability and ability to perform under demanding conditions, making it a popular choice for performance builds. It’s important to note that this camshaft is intended for engines with flat tappet camshafts; it does not fit factory roller small blocks from 1985 and newer, nor does it fit LS-based engines. For 1955-1957 Chevrolet engines, a specific oiling groove is required on the rear journal, and this particular part number does not include it.
