COMP Cams Camshaft Kit CB 270H

If you're looking to wake up your Chevrolet Big Block engine, this COMP Cams CB 270H Hydraulic Flat Cam Kit is a solid option. It's designed for street machines that see daily use and works well with a stock torque converter, especially when paired with headers. This kit is specifically for Big Block Chevrolet engines from 396 to 454 cubic inches that originally came with flat tappet camshafts.

This isn't just a camshaft; it's a complete K-Kit, meaning it includes everything you need for a full installation. You get the CB 270H camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. It also comes with a timing chain set to ensure proper synchronization. For flat tappet applications like this one, assembly lube is included to help with the break-in process, along with decals and instructions to guide you through the installation.

The CB 270H camshaft offers a good balance for a street machine, providing a noticeable bump in performance without being overly aggressive. While it's good for daily driving, expect a slight, rough idle which is common with performance cams. For 396 cubic inch engines, COMP Cams recommends a gear ratio between 3.55 and 3.73, along with a torque converter stall speed of 1800 RPM or higher to best utilize the cam's powerband. This kit is a comprehensive solution for upgrading your engine's valvetrain.
