COMP Cams Camshaft Kit CS 283T HR-107 T

If you're looking to give your classic Chevrolet Small Block a serious dose of performance and a signature choppy idle, this COMP Cams Thumpr camshaft kit is a solid choice. Designed for high-performance street applications, this kit is built around a hydraulic roller camshaft that offers improved power and torque over stock, all while producing that distinctive thumping sound that many enthusiasts love. It's a great way to wake up engines like the 283, 327, or 350, giving them a more aggressive personality and better responsiveness.

This kit features a 227-degree intake and 241-degree exhaust duration at .050 inch lift, with a 107-degree lobe separation angle. This specific grind is tuned to work well with stock torque converters, though it really shines when paired with a 2000+ RPM stall converter and appropriate gearing for optimal street performance. The hydraulic roller design means less friction and wear compared to flat tappet cams, contributing to a longer lifespan and consistent performance. It's important to verify your engine is a flat tappet block, as this cam is not compatible with factory roller blocks from 1985 and newer, or the later LS-based engines.

When installing this camshaft, you'll want to ensure you have the necessary supporting components and follow proper procedures for a hydraulic roller setup. This kit is intended for engines that have been converted to or originally came with a flat tappet camshaft, covering a wide range of Chevrolet Small Blocks from the 1950s through the mid-1990s, excluding later factory roller applications. It's a significant upgrade for those seeking a noticeable change in their engine's character and performance.
