COMP Cams Camshaft CB 47S XE274S-10

This COMP Cams XE274S-10 camshaft is a solid flat tappet grind designed for Chevrolet Big Block 396 to 454 cubic inch engines originally equipped with flat tappet camshafts. It's built to give you a strong boost in mid-range torque and throttle response, making it a popular choice for builds that see a lot of street driving and want that immediate feel when you get on the gas. You'll want to pair this with a torque converter with at least a 2500 RPM stall speed to get the most out of its performance characteristics.

The XE274S-10 features a 236 degrees of intake duration and 242 degrees of exhaust duration at .050 lift, with a .558 inch lift on both intake and exhaust. This camshaft is part of COMP Cams' Xtreme Energy line, known for delivering improved performance over stock grinds. It's a well-built component that can make a notable difference in how your engine performs, especially in the crucial mid-range where you do most of your driving.

This camshaft fits a wide range of Chevrolet vehicles from the late 1960s through the mid-1990s, including popular models like the Chevrolet Impala, Chevelle, and C10 Pickup. Please note that this camshaft is not CARB approved and cannot be shipped to California. Also, be aware that models from 1965-1966 with a 396 c.i.d. engine that have an oiling groove in the rear journal require a specific camshaft; if your engine falls into this category, please contact us for assistance.
