What is the primary benefit of the XE274H camshaft profile?

The XE274H camshaft is designed to significantly boost mid-range torque and improve throttle response. This means you'll feel a stronger pull and quicker reaction from your engine in the RPM range where you'll use it most often.

Does this kit include everything needed for installation?

This kit includes the camshaft, hydraulic lifters, assembly lube, and decals. You will need to source other items such as gaskets, fluids, and potentially a new timing set, depending on the condition of your existing components.

How can I be sure my engine has a flat tappet camshaft and not a roller camshaft?

To confirm, you will likely need to remove the intake manifold or timing cover. Many Chevrolet Small Blocks from the mid-1980s onward gradually transitioned to roller camshafts, so visual inspection is the most reliable method.

Product Details

If you're looking to wake up the mid-range power and throttle response in your Chevrolet Gen 1 Small Block engine, this COMP Cams Cam & Lifter Kit is a solid option. This kit is designed to give you a noticeable increase in torque and responsiveness where you'll feel it most during everyday driving and performance applications. It's a popular choice for builders aiming for that extra kick without going to an extreme setup, often paired with a 2200+ stall torque converter for optimal performance.

Inside this kit, you'll find the XE274H camshaft, which features a 230/236 degree duration at .050 lift, along with a set of hydraulic lifters to match. COMP Cams is well-known for its performance valvetrain components, and this kit reflects that reputation with well-built parts designed for improved performance. The kit also includes assembly lube and decals, making the installation process smoother. Remember to confirm your specific engine is a flat tappet design, as this kit is not compatible with factory roller camshafts found in many later model Small Blocks.

This kit fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 400, and 305. It's a great way to add significant performance to vehicles like classic Camaros, Corvettes, C10 trucks, and Caprices from the 1980s and early 1990s. Always refer to the manufacturer's instructions for proper installation and break-in procedures to ensure you get the most out of this performance upgrade.
