What other modifications are suggested to get the most out of this cam kit?

Product Details

If you're looking to wake up the performance of your Chrysler B or RB series big block engine, this COMP Cams Cam and Lifter Kit is a solid choice. This kit is designed for street performance applications, aiming to give you a noticeable improvement in power and torque, especially when paired with other modifications like a higher stall torque converter, improved exhaust, and a capable carburetor. It's a popular option for those rebuilding or upgrading engines like the 383, 400, 413, 426 Wedge, and 440.

The CRB 294S camshaft profile is engineered to work well with a 3500 RPM stall torque converter and a 10:1 compression ratio, making it suitable for a wide range of street-driven vehicles. For the 440 engine specifically, COMP Cams suggests a 3000+ stall converter, an 800 CFM carburetor, and a gear ratio between 3.91 and 4.30 to really take advantage of this cam's capabilities. This kit includes the camshaft, lifters, assembly lube to ensure proper break-in, and decals for that finishing touch.

This kit is intended for engines with significant modifications and is not CARB approved, meaning it cannot be shipped to California. It's important to ensure your engine build is set up to handle the demands of this performance camshaft, including proper fuel delivery, ignition timing, and cooling system capacity.
