What is the recommended break-in procedure for this camshaft?

It is crucial to follow the manufacturer's specific break-in procedure for this camshaft. This typically involves running the engine at a specific RPM range for a set period immediately after installation to properly lubricate and seat the cam lobes and lifters.

Product Details

If you're looking to wake up the performance of your Chrysler 383, 400, 413, 426 Wedge, or 440 engine, this COMP Cams Magnum camshaft is a solid option. It's designed as a great replacement for a 440 with a 700-800 CFM carburetor or a six-pack setup, offering a noticeable idle in 383 engines and a slight idle in 440s. This cam is often considered the largest you can run with a stock torque converter, making it a popular choice for a significant power bump without needing to change out your entire drivetrain.

This is a hydraulic flat tappet camshaft, meaning it uses hydraulic lifters to maintain zero valve lash automatically, simplifying installation and maintenance compared to solid lifter cams. The 224 degrees of intake and exhaust duration at .050 lift is a well-known profile for providing improved torque and horsepower across a broad RPM range, especially in the mid-range where most street driving happens. COMP Cams is a well-known name in performance engine parts, and this camshaft is built to their standards for reliable performance.

When installing this camshaft, remember to use a quality break-in oil and follow the manufacturer's recommended break-in procedure to ensure proper lubrication and seating of the cam lobes and lifters. This is crucial for the longevity of your new camshaft.
