COMP Cams Cam/Lifter Kit CS 291T HR-107

COMP Cams is well-known for its performance camshafts and valvetrain components, and this Mutha' Thumpr hydraulic roller cam and lifter kit is a prime example of their expertise. This kit is designed for high-performance street and strip applications, specifically for OE roller Small Block Chevrolet engines from 1987 and newer, excluding LT-1 and LS1 variants. It's built to work with a range of vehicles, including models like the Chevrolet Camaro, Corvette, and Buick Roadmaster from those years.

This kit includes a camshaft with a 235/249 degree duration at .050 lift and a 107-degree lobe separation angle, along with matching hydraulic roller lifters. To get the most out of this setup, you'll need at least 9:1 compression, a 2500+ RPM stall torque converter, and supporting modifications like an upgraded intake, gears, and headers. Expect a rough idle, which is characteristic of this aggressive camshaft profile, indicating its focus on top-end power.

When installing this kit, remember that it comes with all the necessary components for a complete valvetrain overhaul, including the camshaft, lifters, assembly lube, decals, and instructions. This is a significant upgrade for anyone looking to extract serious performance from their Small Block Chevy, and it's a solid option for builders aiming for a powerful street/strip machine.
