Product Details

This is the COMP Cams 20-721-9 camshaft, a solid roller grind specifically for Chrysler 273, 318, 340, and 360 cubic inch LA-series engines. If you're building a drag car or a serious street/strip machine that needs a strong, reliable power band, this cam is designed to get you there. It's a 'Super Stock' grind, meaning it's built for competitive racing while still being manageable for a dedicated build.

The 274 degrees of intake duration and 279 degrees of exhaust duration, combined with its solid roller design, mean this cam can handle higher RPMs and provide a significant airflow improvement over stock. The solid roller lifters are key here; they reduce friction and allow for more aggressive lobe profiles, which translates directly into more power. This cam is intended for engines where performance is the primary goal, and it's a popular choice for those looking to extract maximum performance from their Mopar LA engine.

When installing a performance camshaft like this, it's important to ensure your valvetrain components are up to the task. This includes matching lifters, pushrods, and valve springs that can handle the increased lift and RPMs. It's also crucial to follow the manufacturer's break-in procedure carefully to ensure the cam lobes and lifters seat properly, which is vital for longevity. This camshaft is not CARB approved and cannot be shipped to California.
