What is the recommended break-in procedure for this camshaft?

It is crucial to follow a specific break-in procedure for hydraulic flat tappet camshafts. This typically involves running the engine at 2000-2500 RPM for about 20-30 minutes immediately after installation to properly seat the lifters and prevent damage.

What type of oil should I use with this camshaft?

For flat tappet camshafts like this one, it is highly recommended to use an oil with a higher zinc content (ZDDP). Modern oils often have reduced zinc levels, which can lead to premature wear on flat tappet systems.

Do I need to change my valve springs when installing this camshaft?

Yes, it is generally recommended to replace your valve springs when installing a new camshaft. The lift and duration specifications of this camshaft may exceed the capabilities of your original valve springs, and using compatible springs is essential for proper engine function and longevity.

Product Details

If you're working on a Chevrolet Big Block engine originally equipped with a flat tappet camshaft, like those found in a 1967 Chevelle or a 1975 Impala, this COMP Cams CB 252AH-10 camshaft is a solid option. This camshaft is designed to fit a wide range of Chevrolet applications from the late 60s through the early 90s, including popular models like the Camaro and Corvette.

This camshaft features a 252 degrees of intake duration and 252 degrees of exhaust duration at .050 inch lift, with a .460 inch intake lift and .460 inch exhaust lift. These specs are chosen to provide an improved idle quality and a noticeable bump in low-end torque and horsepower compared to stock, without being overly aggressive for street use. It's built with durable materials to handle the demands of a performance street engine.

When installing this camshaft, remember that it requires a proper break-in procedure to ensure the flat tappets seat correctly. It's also important to use a high-zinc oil formulation to lubricate the flat tappet system effectively. Make sure you have the necessary valve springs and lifters that are compatible with this camshaft's specifications.
