Product Details
If you're building a Pro Street Ford with a 221, 255, 260, 289, or 302 small block engine, this COMP Cams FS 308R Solid Roller Cam Kit is designed to give you the ultimate in performance. This kit is specifically for those looking for a radical idle and serious power, typically paired with a 3500+ stall torque converter and 4.10 or lower rear gears.
This isn't just a camshaft; it's a complete K-Kit, meaning it comes with everything you need to get this high-performance camshaft installed. Inside the box, you'll find the camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. To ensure proper timing, a timing chain set is also included, along with assembly lube and decals. This comprehensive approach means you won't be scrambling for extra parts during your build.
The FS 308R camshaft is a solid roller design, known for its ability to handle higher RPMs and provide more aggressive valve lift compared to hydraulic cams. This translates to improved airflow and more power, especially in the upper RPM range. While this kit offers significant performance gains, it's important to note that it's not CARB approved and cannot be shipped to California. It's a serious upgrade for a serious build, designed for enthusiasts who want to push the limits of their Ford small block.
