COMP Cams Camshaft CS 317E-R6 .900Bc

If you're building a serious drag car with a Chevrolet Small Block Gen 1 engine, you're probably looking for a camshaft that can handle high RPMs and deliver serious power. This COMP Cams CS 317E-R6 .900Bc solid roller camshaft is built for that purpose, designed for engines over 355 cubic inches with ported heads and a high-stall torque converter, typically in lighter vehicles.

This camshaft features a .900-inch base circle, which is important for clearance in some engine builds. It's a solid roller design, meaning it uses roller lifters for reduced friction and increased RPM potential compared to flat tappet cams. COMP Cams has optimized this cam for drag racing, with a duration of 280 degrees on the intake and 292 degrees on the exhaust, and a lift of .900 inches. Remember, for this camshaft to perform correctly and to maintain warranty, it must be used with a Melanized or Nitrided distributor gear. Using a cast or steel gear without these surface treatments will void the warranty.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350 and 400 cubic inch variants. It's important to note that this camshaft is not compatible with factory roller camshaft blocks from 1985 and newer, nor is it compatible with LT1/LT4 or LS-based engines. Also, early 1955-1957 Chevrolet 265 engines require a specific oiling groove on the rear journal; if your engine requires this, please contact us for assistance.
