Product Details
This COMP Cams CRB 305H camshaft kit is built around a Magnum hydraulic flat tappet camshaft with a 253-degree intake and 253-degree exhaust duration. This camshaft is designed for Pro Street applications and is a popular choice for those looking to build a powerful street machine. It requires a 3500-3700+ RPM stall torque converter for 383ci engines or a 3000-3300+ RPM stall converter for 440ci engines, along with an 850 CFM carburetor, 10:1 or higher compression ratio, headers, and a good intake manifold. For optimal performance, a gear ratio between 3.90 and 4.30 is recommended.
This is a complete kit, meaning it includes everything you need to get the job done right. You'll find the 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 valve timing, and assembly lube to help with installation. COMP Cams includes decals and instructions to guide you through the process. This kit is designed to fit a wide range of Chrysler B and RB series engines, including the 383, 400, 413, 426 Wedge, and 440. It's a solid option for vehicles like the Dodge Charger, Plymouth Barracuda, and Chrysler New Yorker from the late 60s and 70s.
When installing this camshaft, remember that it is not CARB approved and cannot be shipped to California. It's important to have the right supporting modifications, such as headers and a good intake, to take full advantage of the camshaft's potential. This kit is a significant upgrade for your engine's performance, especially for street-driven vehicles that see occasional track use.
