What is the difference between a flat tappet and a roller camshaft?

A flat tappet camshaft uses lifters with a flat bottom that slides across the cam lobe, requiring more frequent lubrication. A roller camshaft uses lifters with a roller wheel, reducing friction and wear, and often allowing for more aggressive cam profiles. This kit is specifically for flat tappet engines.

What is included in the COMP Cams SK-KIT?

This kit includes the camshaft, lifters, a timing chain set, assembly lube, and installation decals. It's a comprehensive package to get you started on your camshaft upgrade.

Does this camshaft kit fit my 1990 Chevrolet 350 engine?

This kit fits many Chevrolet 350 engines, but you must verify if your specific engine uses a factory roller camshaft or a flat tappet camshaft. GM began phasing in roller cams around 1985, so checking your intake manifold or timing cover is recommended to confirm compatibility.

Product Details

When you're looking to wake up your Chevrolet Small Block Gen 1 engine, this COMP Cams Xtreme Energy Camshaft Kit is a solid option. What you get in this kit is a camshaft, a set of lifters, and a timing chain set, along with assembly lube and decals to help you get the job done right. This kit is designed to give you excellent response, good mid-range power, and a noticeable idle, making it a popular choice for many builds.

This particular camshaft, the CS XS262S-10XE, features a 224-degree intake and 230-degree exhaust duration with a .477-inch intake and .480-inch exhaust lift. It's a solid flat tappet camshaft, meaning it uses traditional lifters and requires proper lubrication during installation, which is why the kit includes assembly lube. It's built for Chevrolet Gen 1 Small Blocks, covering a wide range of displacements from 262ci up to 400ci, and is known for its strong mid-range performance. Just be sure to check if your specific engine uses a factory roller camshaft, as this kit is for flat tappet applications and will not work with factory roller setups from 1985 and newer.

This kit fits a wide variety of Chevrolet and related vehicles from the 1980s and early 1990s, including models like the Chevrolet Camaro, Corvette, Caprice, and C1500 trucks, as well as Buick and Cadillac models using the small block Chevy engine. It's important to confirm your engine's configuration before ordering, especially regarding the roller versus flat tappet lifter setup.
