What is a solid roller camshaft and what are its benefits?

A solid roller camshaft uses roller bearings on the lobes to reduce friction, allowing for more aggressive cam profiles with higher lift and duration. This generally leads to improved airflow and increased horsepower, especially at higher RPMs, compared to hydraulic camshafts.

What kind of idle can I expect with this camshaft?

This camshaft is described as having a 'rough idle.' This is typical for performance camshafts with significant duration, as the overlap between intake and exhaust valve events at low RPM can create a less smooth idle compared to stock or milder performance cams.

What supporting modifications are recommended for this camshaft?

Given this is a solid roller camshaft designed for performance, it's recommended to use appropriate valve springs, pushrods, and potentially upgraded lifters that are compatible with solid roller designs. A torque converter with a stall speed of 2500 RPM or higher is also recommended to take full advantage of the cam's powerband.

Product Details

When you're looking to get more reliable power out of your Ford 429 or 460 big block engine, this COMP Cams Xtreme Energy solid roller camshaft is a solid option. You'll receive the camshaft itself, ready for installation. This cam is specifically designed for power touring applications, meaning it's built to deliver strong performance on the street while still being manageable for everyday driving, though expect a rougher idle characteristic of performance cams.

This camshaft features a 236/242 degree duration at .050 inch lift and is a solid roller design, which allows for more aggressive valve lift and duration compared to hydraulic cams. This translates to better airflow and more power, especially in the mid to upper RPM range. It's engineered to work well with a 2500+ stall torque converter, making it a good match for vehicles with automatic transmissions that see spirited driving. COMP Cams designed this unit to be relatively easy on other engine components, helping to extend the life of your valvetrain and other associated parts.

This camshaft fits a wide range of Ford and Lincoln vehicles from the late 1960s through the mid-1990s, including popular models like the Ford F-250, Ford LTD, and Lincoln Continental. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting modifications and components, such as appropriate valve springs and pushrods, to match the solid roller design and performance profile of this camshaft.
