Product Details

This COMP Cams Thumpr camshaft and lifter kit features a 227-degree intake and 241-degree exhaust duration, a design choice that contributes to its signature choppy, thumping idle. It's built for Buick 400, 430, and 455 cubic inch V8 engines, offering a high-performance street profile that works well with stock torque converters but really shines when paired with a 2000+ RPM converter and appropriate gearing. This kit is designed to give your classic Buick a noticeable boost in performance while delivering that aggressive sound many enthusiasts look for.

When you open the box, you'll find everything you need to get started: the camshaft itself, a set of matching hydraulic lifters, assembly lube to ensure proper break-in, and decals for that finishing touch. The instructions included will guide you through the installation process. This kit is a popular choice for those looking to wake up the performance of their Buick, especially models like the Electra, LeSabre, or Riviera from the late 60s through the mid-70s. While it's suitable for street use, consider your torque converter and rear-end ratio to maximize its potential.

Keep in mind that this kit is not CARB approved and cannot be shipped to California. It's a significant upgrade for your engine's breathing and timing, so ensure you have the necessary supporting modifications and knowledge for installation, or consult a professional mechanic. The result is an improved street performance with a distinctive idle note.
