What is the primary benefit of using a hydraulic roller camshaft over a flat tappet design?

Hydraulic roller camshafts generally offer reduced friction and improved efficiency compared to flat tappet designs. This can lead to better performance, increased engine longevity, and often better fuel mileage.

What other components should I consider replacing when installing this camshaft kit?

It is highly recommended to replace valve springs and pushrods to match the camshaft's specifications. This ensures proper valve operation and maximizes the performance and reliability of the new camshaft.

Does this kit include everything needed for installation?

The kit includes the camshaft, lifters, assembly lube, and decals. You will need to source compatible valve springs, pushrods, and potentially other related engine components as part of your build.

Product Details

If you're looking to wake up your Chevrolet Big Block engine, this COMP Cams Camshaft and Lifter Kit is a solid choice.

It’s a popular upgrade for those looking for a noticeable difference without sacrificing drivability.

This kit features a hydraulic roller camshaft with intake and exhaust lobes rated at 200 and 206 degrees of duration, respectively, at .050 inch lift. Hydraulic roller setups are known for their efficiency and reduced friction compared to flat tappet designs, which can contribute to better performance and longevity.

This is a well-built kit designed to fit a wide variety of Chevrolet vehicles from the late 60s through the 90s, including popular models like the Chevelle, Camaro, and C10 pickups.

When undertaking this kind of engine work, it's always a good idea to have a fresh set of valve springs and pushrods that match the camshaft's specifications to ensure optimal performance and reliability. Always refer to the included instructions for detailed installation procedures and break-in requirements.
