If you're building a street machine and plan to run a nitrous oxide system, this kit is a solid choice for adding over 125 horsepower.

This kit includes the camshaft itself, a set of lifters, a timing chain set, assembly lube to get everything installed smoothly, and some decals. The camshaft features a 224/236 degree duration with .558/.560 lift and has a High-Energy (HE) design, meaning it's built for durability and performance in applications like this. It's a well-built component that's a popular upgrade for those looking to significantly boost their engine's power output, especially when paired with a nitrous setup.

For the best results, ensure your vehicle is set up with the appropriate stall speed and gear ratio to take full advantage of the camshaft's capabilities.
