Chevy 348/409 XE Hyd Roller Cam XE284HR10

The COMP CAMS Chevy 348/409 XE Hydraulic Roller Cam XE284HR10 is designed for big-block Chevrolet engine builders looking for reliable performance. This camshaft offers the benefits of roller technology while maintaining compatibility with hydraulic lifters, making it suitable for street applications, restorations, and moderate performance builds on classic Chevy 348 and 409 platforms.

Constructed from cast iron, this hydraulic roller camshaft features precisely ground lobes and hardened journals, providing a smooth power band and reducing wear on valvetrain components compared to flat-tappet designs. The XE284HR10 profile is engineered to deliver strong mid-range torque while maintaining adequate overlap for responsive throttle response, and the roller follower design minimizes friction losses across the RPM range.

This camshaft is ideal for builders modernizing original 348/409 engines in full-size Chevrolet trucks and muscle cars who seek power gains without the need for expensive specialty components or extensive machine work. Installation requires standard small-block Chevy timing components and compatible hydraulic roller lifters, though some adjustments may still be necessary based on the specific engine configuration.
