Product Details

This is the COMP Cams Xtreme Energy XR270HR-1 hydraulic roller camshaft and lifter kit, designed for small block Chevrolet engines from 1987 and newer that came with factory roller camshafts. If you're looking to get more out of your 305 or 350 small block, this kit is a solid option. It's built for high-performance applications and is the largest cam that can work with a stock torque converter, giving you a noticeable idle that lets everyone know you mean business.

Inside this kit, you'll find everything you need to get started: the camshaft itself, a set of hydraulic roller lifters, assembly lube to ensure a smooth break-in, and decals. COMP Cams is well-known for their performance valvetrain components, and this kit reflects that reputation. The camshaft features a 218-degree intake and 224-degree exhaust duration at .050 lift, making it a popular choice for those seeking improved power without sacrificing too much streetability. It's designed to work with your engine's factory roller setup, simplifying installation compared to retro-fit hydraulic roller conversions.

This kit fits a wide range of Chevrolet and Buick vehicles from the late 80s through the mid-90s, including popular models like the Chevrolet Camaro, Corvette, C1500, and Buick Roadmaster. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures to get the most out of your new camshaft and lifters.
