COMP Cams Camshaft Kit CS X4 270H-11

When you're ready to build out the top end of your Chevrolet Gen 1 Small Block, this COMP Cams Camshaft Kit CS X4 270H-11 (K-KIT) is a complete package to get you there. This kit includes the camshaft itself, lifters, valve springs, retainers, valve locks, and valve stem seals. You also get a timing chain set to ensure your valvetrain is synchronized, plus assembly lube for proper installation and decals to show off your new performance parts. This kit is designed for engines like the 350, 400, and others, offering strong mid-range power and improved throttle response, especially when paired with headers and appropriate gearing. It's a popular choice for builds that see a lot of street driving and want a noticeable bump in performance.

This kit is specifically for Chevrolet Gen 1 Small Blocks and is designed to work with flat tappet camshafts. It's important to verify your engine's configuration, as many later models from the mid-80s onward gradually transitioned to factory roller camshafts. If you have a factory roller setup or an LT1/LT4 engine, this kit will not be compatible. The camshaft profile in this kit is known for liking headers and gears, and it performs best with a torque converter stall speed of 2200 RPM or higher, making it suitable for modified street applications. The included components are well-built to handle the demands of an upgraded camshaft profile.

This COMP Cams kit is a comprehensive solution for your engine build, providing nearly everything you need to swap out your camshaft and associated valvetrain components. While it includes a timing chain set, always refer to the manufacturer's instructions for specific installation procedures and any additional hardware or tools that might be required for your particular application. This kit is not CARB approved and cannot be shipped to California.
