The COMP Cams XR280 R-10 camshaft targets street machines that need strong torque across the midrange when paired with a 2,800+ rpm stall converter, 10:1+ compression, and 3.73–3.90 rear gears. The profile delivers dependable power for spirited street use but requires a melanized or nitrided distributor gear for compatibility; cast or untreated steel gears are not supported per manufacturer guidance.
