The COMP Cams XR280HR-10 retrofit hydraulic roller cam suits builds with 3.91+ gears and supports 9.5:1 compression and a 2,500+ RPM stall speed. It performs best with aftermarket intake manifolds and headers, offering stronger mid-range and top-end power for street/strip engines where a more aggressive powerband is required without moving to a solid roller.
