What is required for installation of this solid roller camshaft?

As a solid roller camshaft, this part requires a compatible solid roller valvetrain. This includes roller lifters, roller rocker arms, and appropriate pushrods. You should also confirm your engine originally used a flat tappet camshaft, as this is not compatible with factory roller setups from 1985 and newer.

Does this camshaft come with any other components?

Product Details

This COMP Cams CS 318Rxd-14 solid roller camshaft is designed for Chevrolet Gen 1 Small Block engines, specifically those built for drag racing and bracket racing applications. It's intended for larger cubic inch engines looking for significant performance gains. You'll receive the camshaft itself, ready for installation into your compatible engine.

This camshaft features a 285-degree intake duration and 300-degree exhaust duration with a .050 inch lift of 244 degrees on the intake and 252 degrees on the exhaust. The lift figures are .630 inches on the intake and .630 inches on the exhaust, designed to work with 1.8 and 1.7 rocker arm ratios. It's a solid roller design, which means it requires roller lifters, roller rocker arms, and a compatible valvetrain setup. This type of camshaft is known for its ability to achieve higher RPMs and more aggressive valve timing compared to flat tappet designs, making it a popular choice for competitive racing where every bit of performance counts.

It's important to confirm your engine's original configuration. This camshaft is intended for engines that originally used a flat tappet camshaft. If your 1985 or newer Small Block Chevrolet has factory roller lifters, this camshaft will not be compatible. You can verify by removing the intake manifold or timing cover to inspect the lifter style. This camshaft fits a wide range of Chevrolet Small Block Gen 1 engines, including popular displacements like the 350 and 400 cubic inch variants, but does not fit LS-based engines or LT1/LT4 applications. For 1955-1957 Chevrolet 265 engines, ensure there is an oiling groove on the fifth cam journal.
