What is the primary benefit of this camshaft and lifter kit?

This kit offers improved performance with a more aggressive camshaft profile (244/254 duration at .050 lift). It's designed to provide a noticeable increase in power and torque for your Chevrolet Big Block engine, especially in performance applications.

What else might I need to install this kit?

While the kit includes the camshaft, lifters, and assembly lube, you will need to ensure your engine has headers for proper exhaust flow. It's also recommended to check your engine's compression ratio, as this cam works best with 9.5:1 or higher.

Does this kit come with everything needed for the camshaft break-in procedure?

Yes, the kit includes assembly lube and instructions to guide you through the installation and break-in process. Proper break-in is crucial for the longevity of flat tappet camshafts, so follow the included directions carefully.
