What is required to get the most out of this camshaft?

To achieve maximum performance with this camshaft, it's recommended to use headers, a torque converter with a stall speed of 3000 RPM or higher, and a compression ratio of at least 9.5:1. The rough idle is a characteristic of this high-performance cam.

Does this kit include everything needed for installation?

The SK-KIT includes the camshaft, lifters, a timing chain set, and assembly lube. You will need to consult the included instructions for the specific installation procedure and any additional tools or fluids required.

How can I tell if my engine has a flat tappet or roller camshaft?

You will need to remove the intake manifold or timing cover to visually inspect the camshaft. Factory roller camshafts have a different design at the lifter interface compared to the flat tappet design. Many engines from 1985 and newer, especially in Camaros, Firebirds, and Corvettes, came with roller cams.

Product Details

This COMP Cams camshaft kit is built around a Magnum 248/248 solid flat tappet camshaft, designed for maximum street performance in Chevrolet Gen 1 Small Block engines. The 248 degrees of intake and exhaust duration at 0.050 inch lift means this cam will create a very noticeable, rough idle, and it's intended for builds where aggressive performance is the priority. To make the most of this camshaft, you'll want to pair it with headers, a torque converter with at least a 3000 RPM stall speed, and a compression ratio of 9.5:1 or higher.

The SK-KIT includes everything you need to get this camshaft installed and running: the camshaft itself, a set of lifters, a complete timing chain set, assembly lube to ensure proper break-in, and decals. This kit is specifically for Chevrolet Gen 1 Small Blocks, covering a wide range of displacements from 262ci up to 400ci. It's important to verify your engine uses a flat tappet camshaft, as many later models (from 1985 onward) switched to factory roller camshafts. This kit is not compatible with LT1/LT4 engines or any LS-based V8s.
