Product Details

COMP Cams is well-known for making performance engine parts, and this Magnum hydraulic flat tappet camshaft and lifter kit is a solid option for anyone looking to get more out of their Chrysler B or RB series engine. This kit is designed for a Pro Street application, meaning it's built to perform well on the street with some modifications, and it's a popular choice for vehicles like the Dodge Charger, Plymouth Barracuda, and Chrysler New Yorker from the late 50s through the late 70s.

The camshaft in this kit has a 253-degree intake and 253-degree exhaust duration at .050 lift, which is a pretty aggressive profile. For the 383 engine, you'll want a torque converter with a stall speed of at least 3500-3700 RPM, and for the 440, aim for 3000-3300 RPM. You'll also want to pair this with an 850 CFM carburetor, at least 10:1 compression, headers, and a good intake manifold, along with a rear gear ratio between 3.90 and 4.30 to really make it sing. The kit comes complete with the camshaft, lifters, assembly lube, decals, and instructions, so you have most of what you need to get started.
