What type of valvetrain components are needed for this solid roller camshaft?

This is a solid roller camshaft, so it requires a full roller valvetrain. This includes solid roller lifters, roller rocker arms, and compatible pushrods. It's essential to use components designed for solid roller applications to ensure proper function and durability.

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

Solid roller camshafts require a specific break-in procedure immediately after installation to properly seat the lifters and prevent damage. You must follow the manufacturer's instructions, which typically involve running the engine at a specific RPM range for a set duration. Failure to do so can lead to premature wear.

What compression ratio and stall speed are recommended for this camshaft?

For optimal performance with this camshaft, a compression ratio of approximately 9:1 is recommended. It also pairs well with a torque converter that has a stall speed around 2500 RPM, making it suitable for mild street and strip use.

Product Details

This is the COMP Cams Xtreme Energy XR268R-10 solid roller camshaft, designed for Chrysler 273, 318, 340, and 360 cubic inch LA-series engines. If you're looking to build a mild street or strip combination, this camshaft can offer a noticeable idle and improved performance over stock, especially when paired with about 9:1 compression and a 2500 RPM stall torque converter.

The Xtreme Energy line from COMP Cams is known for its ability to make good power across a broad RPM range. This particular camshaft features a 230-degree intake and 236-degree exhaust duration at .050 inch lift, which is a solid profile for a street-driven vehicle that also sees occasional track use. Being a solid roller camshaft, it requires specific valvetrain components like roller lifters, roller rocker arms, and pushrods, and it needs to be properly broken in to ensure longevity. It's important to note that this camshaft is not CARB approved and cannot be shipped to California.

When installing a camshaft like this, it's crucial to follow the manufacturer's break-in procedure meticulously. This typically involves running the engine at a specific RPM range for a set period immediately after installation to properly seat the lifters and prevent premature wear. Ensure you have all the necessary valvetrain components and a good understanding of the installation process before you begin.
