Product Details
COMP Cams is well-known for performance valvetrain components, and this Xtreme Energy XR274R-10 solid roller camshaft kit is a prime example of their expertise. This kit is designed for Chevrolet Big Block engines, specifically those originally equipped with flat tappet camshafts, like the 396, 427, and 454 cubic inch V8s. If you're looking to build a power touring engine that makes serious, reliable power without being overly harsh on other components, this kit is a solid option.
The XR274R cam itself features a 236-degree intake and 242-degree exhaust duration at .050 lift, making it a potent choice for street performance. It's designed to work best with a torque converter that has a stall speed of 2500 RPM or higher, which helps keep the engine in its power band during acceleration. While it produces a rough idle, characteristic of solid roller cams, it offers very reliable power gains and is built to last. This kit includes the camshaft, lifters, a timing chain set, assembly lube, decals, and instructions, so you have the essential pieces to get started on your build.
This kit is intended for a wide range of Chevrolet vehicles from the late 1960s through the 1990s, including popular models like the Chevrolet Impala, Chevelle, and C10 pickup trucks. Remember that solid roller camshafts require specific valvetrain geometry and oiling considerations, so it's always a good idea to consult the included instructions and manufacturer recommendations for proper installation. Please note this part is not CARB approved and cannot be shipped to California.
