COMP Cams Camshaft CS 283T HR-107 T Thu

This COMP Cams Thumpr camshaft is designed for Chevrolet Gen 1 Small Block engines. You'll get the camshaft itself, ready to install. This camshaft is built for high-performance street use and is known for its distinctive choppy, thumping idle sound. It's optimized for use with Melanized or Nitrided distributor gears, so be sure to check your current setup or plan for an upgrade to avoid warranty issues.

The CS 283T HR-107 camshaft features a 227-degree intake duration and 241-degree exhaust duration with a 107-degree lobe separation angle. This hydraulic roller camshaft is a popular choice for enthusiasts looking to give their engine a more aggressive sound and improved performance on the street. While it can work with a stock torque converter, it performs best with a converter rated at 2000 RPM or higher, along with appropriate gearing to match.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 283, 305, 327, and 350. It's important to verify your engine is a factory flat tappet design, as this camshaft is not compatible with factory roller camshafts found in many 1985 and newer GM vehicles, nor is it compatible with LS-based engines. Removing the intake or timing cover is the best way to confirm your engine's configuration.
