What is the main advantage of a solid roller camshaft over a flat tappet camshaft?

Solid roller camshafts use roller lifters that significantly reduce friction compared to flat tappet designs. This allows for more aggressive lobe profiles, leading to better performance, higher RPM capability, and improved engine breathing.

What other components are typically needed when installing this camshaft?

When upgrading to a solid roller camshaft like this one, you'll need compatible solid roller lifters, pushrods, rocker arms, and valve springs. It's crucial to ensure all valvetrain components are matched for optimal performance and reliability.

Does this camshaft come with the necessary lifters and hardware?

This camshaft is sold individually and does not include lifters, pushrods, rocker arms, or other valvetrain components. You will need to source these separately to complete the installation.

Product Details

If you're looking to get more out of your Chevrolet Big Block engine, especially in marine applications or for a performance street build, a camshaft upgrade is a key step. This COMP Cams CB 310A-R8 solid roller camshaft is designed for the 396-454 cubic inch Big Block engines that originally came with flat tappet camshafts. It's a popular choice for those seeking a noticeable increase in power and torque across the RPM range.

This camshaft features a 280-degree intake and 280-degree exhaust duration at .050 inch lift, with a .632 inch intake and .632 inch exhaust lift. The solid roller design means it uses roller lifters, which reduce friction compared to flat tappets, allowing for more aggressive lobe profiles and higher RPM potential. This translates to better breathing for your engine and a more responsive feel. It's well-built with a focus on durability for demanding use, and it's designed to work with the specific valve train geometry of these classic Chevy big blocks.

When installing a solid roller camshaft, it's important to ensure your entire valvetrain is up to the task. This includes using compatible roller lifters, pushrods, rocker arms, and valve springs. Because this is a significant performance upgrade, we recommend consulting the manufacturer's installation instructions carefully to ensure proper break-in procedures are followed, especially for the solid roller components. This camshaft fits a wide range of Chevrolet vehicles from the late 60s through the 90s, including popular models like the Chevelle, Camaro, and C10 pickup.
