Product Details

This COMP Cams Camshaft Kit, specifically the CS XR269HR-12, is built around a hydraulic roller camshaft with a 218-degree intake and 224-degree exhaust duration. This design is well-suited for Tuned Port Injection (TPI) 305 or 350 Small Block Chevrolet engines, especially when you've already upgraded the exhaust system. It’s designed to work with OE roller camshaft setups found in many General Motors vehicles starting in 1987, covering a wide range of popular models like the Chevrolet Camaro, Corvette, and various C/K series trucks.

When you choose this K-Kit, you're getting a complete package to ensure a smooth and successful installation. It includes the camshaft itself, hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. COMP Cams also bundles in a timing chain set, and for applications like this one that use flat tappet designs, you'll find assembly lube included. This comprehensive approach means you won't have to hunt for individual components, saving you time and ensuring compatibility between parts. Keep in mind that installing a camshaft like this often requires custom tuning for the engine control unit (ECU) to optimize performance and drivability, so plan for that step after installation.

This kit is a substantial upgrade for your engine's breathing capabilities. The specific lobe profile of the XR269HR camshaft is chosen to improve airflow, particularly when paired with better exhaust systems. It’s a popular choice for enthusiasts looking to extract more power from their Small Block Chevy, offering a noticeable improvement in throttle response and overall engine output. Remember that this kit is intended for use with factory roller camshaft configurations and is not compatible with LT-1 or LS1 style engines.
