COMP Cams Camshaft FF 300A-R10

COMP Cams is well-known for making performance valvetrain components, and this FF 300A-R10 mechanical roller camshaft is a prime example of their expertise for Ford Big Block engines. If you're building a serious street machine or a dedicated drag car, this camshaft is engineered to give you a noticeable bump in performance. It's designed for engines with a 4000+ RPM stall speed torque converter and a 4-speed transmission, making it ideal for applications where you need to get into the powerband quickly and keep it there.

This camshaft features a radical idle, which is a direct result of its aggressive profile. It's intended for engines running 11:1 or higher compression ratios, meaning it's built for maximum power output. The mechanical roller design means less friction and more precise valve timing compared to flat tappet cams, allowing for higher lift and duration without excessive wear. This translates to better airflow and more power, especially at higher RPMs. It's a popular choice for those looking to extract the most out of their Ford 429 or 460 cubic inch engines.

This camshaft fits a wide range of Ford and Mercury vehicles from the late 60s through the 90s, including models like the Ford F-250, Ford LTD, and Mercury Marquis. When installing a camshaft like this, it's crucial to ensure all supporting components are up to the task. This includes checking your valve springs, pushrods, and lifters to make sure they can handle the increased lift and RPMs. It's also important to follow the manufacturer's break-in procedure carefully to ensure the longevity of the cam and lifters.
