What type of valvetrain does this camshaft require?

This COMP Cams camshaft is a hydraulic flat tappet design. It requires an engine block and valvetrain components designed for flat tappet camshafts, and is not compatible with factory roller camshaft systems.

What kind of idle can I expect with this camshaft?

The Xtreme Energy XE274H-10 is designed to provide a smooth idle while still offering significant performance improvements. It aims to bridge the gap between street cams and race cams, so while it's more aggressive than stock, it's intended for quiet operation in daily driven vehicles.

What other parts might I need when installing this camshaft?

When installing a new camshaft, it's generally recommended to replace the valve springs, lifters, and pushrods to ensure optimal performance and longevity. A new timing set is also a good idea. Always refer to the manufacturer's installation instructions for a complete list of recommended components.

Product Details

This COMP Cams Xtreme Energy camshaft is a hydraulic flat tappet grind designed for Chevrolet Small Block engines. You'll get a noticeable increase in mid-range torque and throttle response, making it a popular choice for street-driven vehicles that see regular use. It bridges the gap between milder street cams and more aggressive race-only grinds, offering improved power without sacrificing too much in terms of idle quality or valve train noise.

The XE274H-10 features a 230/236 degree intake/exhaust duration and is designed to work well with a 2200+ stall torque converter, making it suitable for a wide range of Chevrolet Small Block applications from 1955 through the mid-1990s, provided your engine uses a flat tappet valvetrain. It's built for durability in daily driven vehicles, aiming for quiet operation while still delivering the performance gains you're looking for.

This camshaft is a solid option if you're looking to wake up the powerband of your classic Chevy V8. Remember to verify your engine's valvetrain type (flat tappet vs. roller) before installation, as this cam is specifically for flat tappet blocks.
