COMP Cams Camshaft CRB3 XR274R-10

If you're looking to get more performance out of your Chrysler 383, 400, 413, 426 Wedge, or 440 engine, this COMP Cams Xtreme Energy camshaft is a solid option. It's designed to give you a noticeable bump in torque and horsepower by opening the valves quicker and creating a more effective lift curve. This means better responsiveness from your engine without making it difficult to drive around town or impacting essential systems like power brakes, which still get adequate vacuum.

This camshaft is a popular choice for street builds, especially when paired with a 2500+ stall torque converter and a 9.5:1 compression ratio. While it works well with carbureted setups, you'll see the best results when you combine it with aftermarket intake manifolds, lower gear ratios, headers, and a free-flowing exhaust system. The solid roller design means it's built for higher RPMs and more aggressive valve lift compared to flat tappet cams, offering a significant performance improvement for those seeking more power.

This camshaft is designed for a 3-bolt mounting pattern and fits a wide range of Chrysler B and RB series engines from the late 1950s through the late 1970s, including popular models like the 1970-1971 Dodge Challenger and the 1966-1978 Dodge Charger. It's a direct fit for many classic Mopar vehicles, making it a great way to wake up the performance of your vintage muscle car.
