COMP Cams Camshaft CS 281Qio8

COMP Cams has built a reputation for making serious performance parts for race cars and street machines. This particular camshaft, the CS 281Qio8, is a hydraulic roller design built for Chevrolet Small Block engines. It's a great all-around choice if you've got a modified engine and are running a manual transmission or an automatic with a torque converter rated at 2500 RPM or higher. You'll need to have upgraded valve train components and aftermarket cylinder heads to make this camshaft work properly.

What makes this cam stand out is its 4-pattern design. This means the valve events are optimized based on the runner length of your intake manifold. This approach helps increase the area under the power curve, leading to better overall performance and improved stability at higher RPMs. The camshaft uses retro-fit link bar hydraulic roller lifters, which are a popular upgrade for their reduced friction and improved durability compared to flat tappet designs. Remember, COMP Cams strongly recommends using a melanized or nitrided distributor gear with this camshaft to avoid voiding your warranty.

This camshaft fits a wide range of Chevrolet Small Block engines from 1958 through 2002, including popular displacements like the 350 and 400 cubic inch V8s. It's important to verify your specific engine block is not a factory roller setup from 1985 or newer, as this cam is designed for earlier flat tappet blocks. If you're looking to get more out of your modified street machine, this camshaft is a solid option from a well-known performance brand.
