COMP Cams Camshaft Kit P8 299Th R7 Thumper

When you're ready to really wake up your Pontiac V8, this COMP Cams Big Mutha' Thumpr Cam Kit is what you'll want. This kit gives you everything you need to install a serious hydraulic roller camshaft designed for aggressive street and strip use. You're getting the camshaft itself, lifters, valve springs, retainers, valve locks, valve stem seals, a timing chain set, and even assembly lube to make sure everything goes together right. Plus, you get decals and instructions to guide you through the process.

This is the P8 299Th R7 Thumper camshaft, which has a 243-degree intake and 257-degree exhaust duration. It's built for Pontiac 265 to 455 cubic inch V8 engines and is designed to work best with about 9.5:1 compression. You'll also need a 2800+ RPM stall torque converter, an upgraded intake manifold, rear gears, and headers to really take advantage of what this cam can do. Expect a very rough idle with this setup – it's meant for performance and lets everyone know it.

This kit is a comprehensive way to upgrade your engine's valvetrain for a significant performance change. Remember, this camshaft is not CARB approved and cannot be shipped to California. Make sure your Pontiac V8 is ready for this kind of aggressive performance upgrade.
