BBC Xtreme Roller Cam XR292R-10

The BBC Xtreme Roller Cam XR292R-10 from COMP CAMS is designed specifically for big-block Chevrolet engines that require aggressive performance and reliability. This roller cam assembly is ideal for street and strip applications, where enhanced valve lift and duration can lead to significant horsepower gains and improved throttle response. Whether you're building a restomod, performance cruiser, or dedicated race engine, this cam provides the mechanical advantage that serious enthusiasts seek.

The XR292R-10 designation indicates aggressive valve timing optimized for mid to high-RPM power delivery. The roller followers are made of hardened steel and feature precision-ground profiles that maintain exact valve actuation geometry throughout the engine's operational range. This roller technology minimizes friction and wear compared to flat-tappet designs, allowing for sustained high-RPM operation without cam lobe degradation.

This cam is particularly beneficial for BBC enthusiasts utilizing solid roller valvetrains, whether in naturally aspirated or boosted configurations. It is crucial to ensure compatibility with lifters and verify valvetrain geometry during installation, as improper setup can lead to valve-to-piston contact and catastrophic engine damage. The cam is suitable for big-block Chevrolet platforms from 1965 to present, provided they meet the necessary specifications.
