What kind of idle can I expect with this camshaft?

This Xtreme Energy camshaft is designed for performance and will result in a rougher idle compared to a stock camshaft. This is typical for cams with this duration and lift profile, indicating it's optimized for power rather than quiet operation.

What other parts do I need to install this camshaft?

For optimal performance, it's recommended to pair this camshaft with a torque converter rated for 3000+ RPM, headers, and suitable rear-end gearing. You will also need to follow the proper break-in procedure for hydraulic flat tappet camshafts.

Is this camshaft CARB approved?

No, this camshaft is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

With a 240/246 degree intake/exhaust duration, this COMP Cams Xtreme Energy camshaft is built for Chrysler LA-series engines from 273 to 360 cubic inches. It's designed for street/strip applications where you're looking for a noticeable bump in performance, but it does come with some trade-offs you should be aware of. You'll want to pair this with a higher stall torque converter, likely 3000 RPM or more, along with headers and appropriate rear-end gearing to really let it breathe and put the power down effectively. Expect a rougher idle than stock, which is part of its aggressive nature.

This camshaft is a well-built component for those looking to modify their classic Mopar. It's a hydraulic flat tappet design, meaning it uses standard lifters and requires proper break-in procedures to ensure longevity. COMP Cams is a well-known name in performance valvetrain components, and this XE series cam is a popular choice for enthusiasts seeking improved power output from their LA-based V8s. It's a solid option for building a street machine that can also handle some track time.

This camshaft fits a wide range of Chrysler, Dodge, and Plymouth vehicles from the mid-60s through the early 90s, including popular models like the Dodge Challenger, Charger, and Plymouth Duster. Make sure to check the full fitment list to confirm it's right for your specific application.
