Product Details

If you're building a serious street or strip Mopar with a Chrysler B or RB engine, this COMP Cams Cam and Lifter Kit is designed to give you strong mid-range power. This kit is specifically tuned for applications running around 9.5:1 compression and a 2800+ RPM stall speed torque converter, making it a popular choice for those looking to extract more performance from their 383, 400, 413, 426 Wedge, or 440 cubic inch engines.

The Xtreme Energy XS274S-1 camshaft profile is engineered to deliver noticeable improvements in the mid-range RPM band, which translates to better acceleration and a more responsive feel when you're on the throttle. This kit includes the camshaft, a set of matching lifters, assembly lube to ensure proper break-in, and decals for that custom engine bay look. COMP Cams is well-known for its performance camshafts, and this kit offers a well-built package for Mopar enthusiasts looking to upgrade their engine's breathing capabilities.

This kit is intended for performance builds and is not CARB approved, meaning it cannot be shipped to California. Always refer to the included instructions for proper installation and break-in procedures to ensure optimal performance and longevity of your new camshaft and lifters.
