What kind of idle can I expect with the COMP Cams XR292HR-10 camshaft?

This camshaft is designed for aggressive performance applications and will produce a very rough idle. This is characteristic of high-performance cams intended for Pro Street and bracket racing use.

What supporting modifications are recommended for this camshaft?

For optimal performance and reliability, it's recommended to pair this camshaft with a 4.10 gear ratio, a 3000+ RPM stall torque converter, and a 10:1 compression ratio. You will also need to ensure your valvetrain components, such as valve springs, pushrods, and lifters, are compatible with its specifications.

Can this camshaft be used in a stock 426 HEMI engine?

This is a retro-fit hydraulic roller camshaft. While it can be installed in engines originally equipped with flat tappet cams, it requires the addition of roller lifters and potentially other supporting hardware. It is also designed for specific compression ratios and gear ratios not typically found in stock configurations.

Product Details

If you're building a serious Pro Street or bracket racing machine with a Chrysler 426 HEMI, this Xtreme Energy XR292HR-10 camshaft from COMP Cams is designed to give you the aggressive performance you're looking for. This is a retro-fit hydraulic roller camshaft, meaning it's designed to work with your existing hydraulic roller valvetrain components or can be installed in engines that originally had flat tappet cams with the addition of roller lifters and the necessary supporting hardware. It's engineered for engines with a 4.10 gear ratio, a 3000+ RPM stall torque converter, and a 10:1 compression ratio, making it suitable for high-performance street and strip applications.

The XR292HR-10 features a 242-degree intake and 248-degree exhaust duration at .050 inch lift, with .520 inch lift on both the intake and exhaust. This aggressive profile is what gives it that very rough idle characteristic that many performance enthusiasts associate with serious drag racing engines. The hydraulic roller design helps reduce friction and wear compared to flat tappet cams, allowing for more aggressive lobe profiles and improved valvetrain stability at higher RPMs. COMP Cams is well-known for its performance camshafts, and this Xtreme Energy series is a popular choice for those looking to extract maximum power from their Mopar big blocks.

Keep in mind that this camshaft is not CARB approved and cannot be shipped to California. It's intended for competition or off-road use where emissions regulations may not apply. Ensure your engine's supporting components, such as valve springs, pushrods, and lifters, are compatible with the lift and duration specifications of this camshaft to achieve optimal performance and reliability.
