What type of distributor gear should I use with this camshaft?

This camshaft is optimized for use with a melanized or nitrided distributor gear. Using cast or steel gears without similar surface treatments will void all warranties and return policies.

Can I use this camshaft in my 1990 Chevrolet 350 engine?

Yes, this camshaft fits many Chevrolet Small Block engines from 1958-2002. However, if your 1990 350 engine is a factory roller setup, you may need specific installation components. It's recommended to check your block for factory roller provisions.

What is the main performance benefit of this camshaft?

This camshaft is designed to provide a good increase in mid-range power and torque. It's particularly well-suited for street performance and off-road applications where strong low and mid-range pull is beneficial.

Product Details

COMP Cams is well-known for making performance parts that help engines run better, especially for enthusiasts looking to get more out of their vehicles. This CS X4 260HR-11 camshaft is built for Chevrolet Small Block engines, specifically designed to give you a good increase in mid-range power. It’s a hydraulic roller camshaft, which means it uses roller lifters to reduce friction compared to flat tappet designs, helping it perform better and last longer.

This camshaft is optimized for use with a melanized or nitrided distributor gear to ensure proper function and longevity. It’s designed to work well with a stock torque converter, making it a popular choice for street performance and off-road applications where you need strong low and mid-range torque. The Xtreme 4x4 series lobes are a bit more aggressive than the original Xtreme Energy series, offering a noticeable performance improvement without being too radical for daily driving or trail use. It fits a wide range of Chevrolet Small Block engines from 1958 through 2002, including popular displacements like the 350 and 400 cubic inch V8s found in vehicles like the Chevrolet C10, Camaro, and Caprice.

When installing this camshaft, it's important to use the correct distributor gear as specified by COMP Cams. If your engine is an '87 or newer Small Block that came with provisions for roller lifters but doesn't have the roller components installed, you may need a COMP Hydraulic Roller Lifter Install Kit. Always refer to the manufacturer's installation instructions for complete details and compatibility checks, especially for specific engine year variations.
