COMP Cams Camshaft Kit B455 279T H-107

If you're looking to give your classic Buick a serious performance boost and that unmistakable choppy idle, this COMP Cams Thumpr camshaft kit is a solid choice. This kit is designed for Buick 400, 430, and 455 cubic inch V8 engines, commonly found in models like the Electra, LeSabre, and Riviera from the late 60s through the mid-70s. It’s built for high-performance street use, and while it can work with a stock torque converter, you'll see the best results with a 2000+ RPM converter and appropriate rear-end gearing to match the camshaft's aggressive profile.

This isn't just a camshaft; it's a complete K-Kit designed to make your engine build smoother. Inside the box, you'll find the B455 279T H-107 camshaft itself, along with all the necessary valvetrain components: lifters, valve springs, retainers, and valve locks. It also includes valve stem seals to ensure proper sealing, a new timing chain set for accurate valve timing, and assembly lube to get everything started right. COMP Cams even throws in decals and instructions to help guide you through the installation process. The 'Thumpr' designation means you can expect a noticeable, aggressive idle that lets everyone know you mean business.

When installing this kit, remember that it's intended for high-performance street applications. The camshaft profile is designed to provide improved power, especially in the mid-to-upper RPM range, and the choppy idle is a signature characteristic. Ensure your engine's cooling system and fuel delivery are up to the task of handling the increased performance. Because this kit is designed for performance, it is not CARB approved and cannot be shipped to California.
