COMP Cams Camshaft CS 283T HR-107 T Thu

This is the COMP Cams Thumpr camshaft, part number 08-600-8. It's a hydraulic roller camshaft designed for OE roller Small Block Chevrolet engines. You'll get the camshaft itself, ready to be installed into a wide range of vehicles from the late 80s through the mid-90s, including models like the Chevrolet Camaro, Corvette, and various C/K series trucks.

This camshaft features a 227-degree intake and 241-degree exhaust duration with a 107-degree lobe separation angle. This specific combination is what gives the Thumpr series its signature choppy, thumping idle that many enthusiasts look for. It's built for high-performance street use and works with a stock torque converter, though it really shines with a 2000+ RPM stall converter and appropriate gearing to take full advantage of its powerband. The hydraulic roller design means it's designed for engines that came with factory roller lifters, making installation more straightforward if your engine is already set up for them.

When considering this camshaft, remember that it's intended for engines with factory roller camshafts, so it won't fit LT-1 or LS1 style engines. While it can work with a stock converter, upgrading to a higher stall converter and suitable rear-end gears will significantly improve its performance characteristics and make that distinctive idle more manageable. This is a popular choice for those looking to give their classic Small Block Chevy a noticeable performance boost and a sound that stands out.
