Product Details

This is the COMP Cams 54-600-11 Thumpr camshaft, a hydraulic roller grind specifically for GM LS GEN III and GEN IV engines. If you're looking to give your LS-powered vehicle a more aggressive sound and a noticeable bump in performance for street driving, this camshaft is a solid option. It's designed to work with stock converters, though it really shines when paired with a 2000 RPM or higher stall converter and appropriate gearing, making it a popular choice for street/strip builds or performance-oriented daily drivers.

The '219/233' in its name refers to the intake and exhaust duration at 0.050 inches of lift, which are key figures that determine how long the valves stay open. This particular grind is known for producing that signature choppy, thumping idle that many enthusiasts associate with performance camshafts. It's a well-built component that aims to improve throttle response and overall power output without requiring extensive modifications to your engine's valvetrain, assuming your cylinder heads are compatible with hydraulic roller setups.

When installing this camshaft, remember that it's intended for high-performance street use. While it can work with a stock torque converter, you'll see the best results and a more manageable driving experience with an aftermarket converter and a rear gear ratio that complements the camshaft's powerband. This camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding valve springs, pushrods, and break-in procedures.
