COMP Cams Camshaft CB 283T HR-107 T Thu

If you're looking to give your Chevrolet Big Block engine a more aggressive sound and improved street performance, this COMP Cams Thumpr camshaft is a solid choice. This hydraulic roller camshaft is designed for high-performance street applications and is known for producing that distinctive choppy, thumping idle that many enthusiasts appreciate. It's a significant upgrade over stock flat tappet camshafts, offering better valve lift and duration for increased airflow and power.

This camshaft features a 227-degree intake duration and a 241-degree exhaust duration, with a 107-degree lobe separation angle. While it can work with a stock torque converter, it really shines when paired with a 2000+ RPM stall converter and appropriate gearing, allowing you to take full advantage of its performance potential. The hydraulic roller design means less friction and wear compared to flat tappet systems, contributing to a longer lifespan and more consistent performance. It's built for Chevrolet Big Block engines like the 396, 427, and 454, and is compatible with a wide range of vehicles from the 1960s through the 1990s, including popular models like the Chevrolet Impala, Chevelle, and C10 pickups.

When installing this camshaft, it's important to follow the manufacturer's instructions carefully, especially regarding break-in procedures for hydraulic roller systems. Ensure you have the correct valve springs and pushrods to match the camshaft's specifications for optimal performance and reliability. This camshaft is not CARB approved and cannot be shipped to California.
