What is the primary benefit of this camshaft over a stock one?

This COMP Cams Xtreme Energy camshaft offers a 220/230 duration at .050 lift, which is more aggressive than stock. This allows the engine to breathe better, resulting in improved horsepower and torque, especially in the mid to upper RPM range.

Do I need to upgrade my valve springs and other valvetrain components?

Yes, it is highly recommended to upgrade your valve springs, pushrods, and potentially lifters when installing a camshaft with increased lift and duration. These components should be compatible with the camshaft's specifications to ensure reliable performance and prevent damage.

What is the break-in procedure for this camshaft?

Always refer to the manufacturer's specific installation instructions for the recommended break-in procedure. Typically, hydraulic roller camshafts require a specific break-in period at a higher RPM for a set duration to properly seat the lobes and ensure longevity.

Product Details

This COMP Cams Xtreme Energy camshaft features a 220 degrees of intake duration and 230 degrees of exhaust duration at .050 inch lift. This hydraulic roller camshaft is specifically designed for GM LT1 and LT4 engines, commonly found in performance applications from the early to mid-90s. It's a well-built component that can significantly change how your engine breathes and performs, offering a noticeable step up from stock.

The Xtreme Energy line from COMP Cams is known for its ability to deliver improved power and torque across a broader RPM range compared to milder cams. This particular grind, the 276HR-14, is engineered to work with the factory hydraulic roller valvetrain, simplifying installation for those looking to upgrade their LT1 or LT4. You can expect a more aggressive idle and a stronger pull through the mid-range and upper RPMs, making it a popular choice for street/strip builds or performance street cars.

When installing a camshaft like this, it's crucial to ensure your valvetrain components are in good condition. This includes checking your lifters, pushrods, and valve springs to make sure they can handle the increased lift and duration. It's also a good idea to have a fresh set of timing components and a proper break-in procedure in mind. Remember, this camshaft is not CARB approved and cannot be shipped to California.
