How do I know if my Chevrolet Small Block engine has a flat tappet camshaft?

You'll need to remove the intake manifold or timing cover to inspect the camshaft. If the lifters are separate pieces that ride directly on the cam lobes, it's a flat tappet. If the lifters have rollers that contact the cam, it's a roller camshaft, and this kit will not be compatible.

What kind of idle can I expect with the COMP Cams CS 270H camshaft?

This camshaft is designed for high performance and will produce a mild, rough idle. This is a common characteristic of cams that offer improved performance over stock and helps indicate the engine is operating in its powerband.

Does this kit come with everything needed for installation?

The kit includes the camshaft, lifters, assembly lube, and decals. You will need to source other installation items such as gaskets, timing set, and potentially new pushrods or valve springs depending on your existing setup.

Product Details

If you're looking to get more performance out of your Chevrolet Small Block Gen 1 engine, this COMP Cams CS 270H Cam and Lifter Kit is a solid option. This kit is designed to work with engines like the 350, 305, and 400, offering a noticeable bump in power, especially when paired with a higher stall torque converter or lower gearing. It's a popular choice for those wanting a bit more aggressive feel without going to an extreme setup.

This kit includes the camshaft, lifters, assembly lube, and decals to get you started. The CS 270H camshaft itself is a hydraulic flat tappet design, meaning it uses a stock-style valvetrain that's generally easier to install and set up compared to roller cams. While it can work with a stock torque converter, you'll see improved results with a 2000+ RPM stall converter, which helps keep the engine in its powerband during acceleration. Expect a mild, rough idle with this cam, which is characteristic of its performance profile.

It's important to confirm your engine uses a flat tappet camshaft before purchasing. Many later model Small Blocks, especially those from 1985 and newer, came factory-equipped with roller camshafts. Checking your intake manifold or timing cover will help you determine if your engine is compatible. This kit is not CARB approved and cannot be shipped to California.
