Product Details

This COMP Cams Xtreme Energy camshaft, part number 23-701-9, is built with a solid roller design and features a 242 degrees of intake duration and 248 degrees of exhaust duration at 0.050 inch lift. It's specifically designed for Chrysler B and RB series engines, including the 383, 400, 413, 426 Wedge, and 440 cubic inch displacements. The three-bolt camshaft design ensures a secure and stable installation, which is crucial for maintaining consistent valve timing and performance under demanding conditions. This camshaft is intended for builds aiming for around 9.5:1 compression and a 3000+ RPM stall speed torque converter, promising a strong mid-range power band and a noticeable, lopey idle that enthusiasts often seek.

The Xtreme Energy series from COMP Cams is known for its ability to wake up an engine, and this XR280R-10 profile is no exception. It's engineered to provide a significant boost in the mid-RPM range, making it ideal for applications where you need strong acceleration out of corners or for passing. While it offers a more aggressive idle, it remains a popular choice for street-driven vehicles that also see track time or performance driving. The solid roller lifter design allows for higher RPM capabilities and more aggressive cam profiles compared to hydraulic lifters, contributing to its enhanced performance characteristics.

This camshaft is a substantial upgrade for your Chrysler B or RB engine, designed to work best with a compatible valvetrain setup, including appropriate valve springs, retainers, and lifters. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Always consult the manufacturer's installation instructions for proper setup and break-in procedures to ensure optimal performance and longevity of your new camshaft and engine.
