What is the main benefit of using a hydraulic roller camshaft?

Hydraulic roller camshafts offer improved performance and longevity compared to traditional flat tappet designs. The roller lifters reduce friction and wear on the camshaft lobes, and they automatically adjust to maintain proper valve lash, meaning less maintenance for you.

What is the recommended exhaust system for this camshaft?

COMP Cams recommends a good exhaust system to help the engine breathe freely and achieve optimal mid-range power gains with this camshaft. While specific exhaust systems aren't listed, a less restrictive dual exhaust setup is generally beneficial for performance camshafts.

Does this kit include everything needed for installation?

This kit includes the camshaft, hydraulic roller lifters, assembly lube, and decals. You will need to source other installation components such as gaskets, timing set, and potentially new valve springs if your current ones are not compatible with the camshaft's lift specifications. Always refer to the manufacturer's instructions for a complete list of recommended parts.

Product Details

If you're looking to get more mid-range power out of your classic Small Block Chevy, this COMP Cams Cam & Lifter Kit is a solid choice. This kit is specifically designed for engines with a factory roller camshaft, like those found in many '87 and newer Chevrolet and GMC trucks, muscle cars, and even some marine applications. It's a popular upgrade for jet boats looking for improved performance with an 'A' or 'B' impeller, and it really shines when paired with a good exhaust system.

The XR276HR-1 camshaft profile is engineered to deliver strong pulling power in the middle of the RPM range, making your vehicle feel more responsive during everyday driving and when you need to accelerate. This kit includes the camshaft itself, a set of hydraulic roller lifters that reduce friction and wear compared to flat tappet designs, assembly lube to ensure proper break-in, and decals. The hydraulic roller design means you get improved performance and longevity without needing to constantly adjust valve lash, as the lifters automatically compensate for expansion and wear.

This kit is a comprehensive package for upgrading your engine's performance. While it's designed for a wide range of vehicles, including models like the Chevrolet Camaro, Corvette, and various C/K series trucks from the late 80s and 90s, it's important to ensure your specific application uses a factory roller camshaft. For optimal results, COMP Cams recommends pairing this camshaft with a good exhaust system to help the engine breathe freely and maximize the power gains in the mid-range.
