COMP Cams Camshaft Kit CRB 306S

When you're ready to build a serious street or strip engine for your Chrysler B or RB series vehicle, this COMP Cams Camshaft Kit K21-249-4 is a complete package to get you there. Inside this box, you'll find the CRB 306S camshaft itself, along with a full set of lifters, valve springs, retainers, valve locks, and valve stem seals. It also includes a timing chain set to ensure proper synchronization, and assembly lube for flat tappet applications. Plus, you get decals and instructions to help guide your installation.

This kit is specifically tuned for Chrysler 383, 400, 413, 426 Wedge, and 440 cubic inch engines. For a 440 engine, COMP Cams recommends a 3500 RPM stall torque converter and at least 10.5:1 compression with an 800-850 CFM carburetor to really make this camshaft shine. If you're working with a 383 engine, you'll want a higher stall converter, around 4000 RPM, to take full advantage of the camshaft's profile. This setup is built for aggressive performance on the street and at the drag strip.

This kit is a solid option for those looking to significantly upgrade their engine's performance. It's designed to work with a range of Chrysler B/RB engines found in vehicles like the Dodge Charger, Plymouth Barracuda, and Chrysler Imperial from the late 1950s through the late 1970s. Remember that this part is not CARB approved and cannot be shipped to California.
