COMP Cams Camshaft Kit CRB3 XS274S-10

If you're looking to get more performance out of your Chrysler 383, 400, 413, 426 Wedge, or 440 engine, this COMP Cams Xtreme Energy XS274S-10 Camshaft Kit is a solid option. This kit is designed for the Mopar B and RB engine families, offering an updated valvetrain profile that can make a noticeable difference in power and torque. It's a popular choice for those rebuilding or modifying these classic big-block Mopar engines, fitting a wide range of vehicles from 1959 through the late 1970s, including models like the Chrysler New Yorker, Dodge Charger, and Plymouth Barracuda.

This isn't just a camshaft; it's a complete valvetrain package. COMP Cams includes everything you need to swap out your old setup and install the new one. You'll find the camshaft itself, a set of lifters, the correct valve springs, retainers, and valve locks to match. It also comes with valve stem seals for proper sealing, a new timing chain set to ensure your timing is spot on, and assembly lube to help get everything installed smoothly. This comprehensive approach means you won't be hunting for individual parts, saving you time and hassle during your build.

The XS274S-10 profile is known for its aggressive ramp speeds and duration, designed to deliver improved performance, especially in the mid-to-upper RPM range. This kit utilizes a 3-bolt camshaft design, which is standard for these Mopar big blocks. While this kit is designed for performance, it's important to note that it is not CARB approved and cannot be shipped to California. Always refer to the included instructions for proper installation and break-in procedures to get the most out of your new valvetrain.
