Product Details

This COMP Cams camshaft kit features a 226/236 degree duration split with high-performance valve springs, designed to give your Chevrolet Big Block engine a strong mid-range pull and improved throttle response. It's built for engines originally equipped with flat tappet camshafts, offering a noticeable idle that lets you know it's working. This kit is a solid option for those looking to wake up their 396, 427, or 454 cubic inch V8.

The SK-Kit includes everything you need to get the job done: the camshaft itself, a set of lifters, a new timing chain set for precise valve timing, assembly lube to protect components during initial startup, and decals. This comprehensive package means you won't be scrambling for extra parts. The hydraulic flat tappet design is a popular choice for its balance of performance and reliability in these classic V8s.

This kit is intended for a wide range of Chevrolet vehicles from the late 60s through the early 80s, including popular models like the C10 Pickup, Impala, and Chevelle. While it offers a noticeable idle and improved performance, it's important to note that this kit is not CARB approved and cannot be shipped to California.
