Product Details

If you're looking to wake up your Chevrolet Big Block engine, this COMP Cams CB 270S Camshaft Kit is a solid choice. Designed for engines originally equipped with flat tappet camshafts, this kit is good for everyday driving and works well when paired with headers. It's a complete package that aims to give your 396, 402, 427, or 454 cubic inch engine a noticeable boost in performance without making it difficult to live with on a daily basis.

This kit includes everything you need to get the job done right: the CB 270S camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. You'll also find a timing chain set, assembly lube specifically for flat tappet applications, and decals. COMP Cams is well-known for its engine building expertise, and this kit reflects that with its carefully chosen specifications. The 224/224 duration on a 110-degree lobe separation angle offers a slightly rough idle, which is a common characteristic of performance cams, but it contributes to improved throttle response and works well with headers. For 396-402 cubic inch engines, you might consider using slightly lower gears to take full advantage of the improved powerband.

This kit is designed to fit a wide range of Chevrolet vehicles from the late 1960s through the mid-1980s, including popular models like the Chevrolet Impala, Chevelle, and C10 Pickup. It's a comprehensive solution for anyone looking to enhance the performance of their classic Big Block Chevy. Remember to consult the included instructions for proper installation and to ensure all components are set up correctly for optimal performance and longevity.
