Developed through extensive research and development, including dyno testing of more than 50 combinations of cam durations, lobe separations, and installation centerlines, this performance camshaft is optimized for \u003cstrong\u003eCummins engines\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eStarting off, let's go over the Stage 3 \"Big Stick\" camshaft which is designed to deliver \u003cstrong\u003estrong mid-range torque and horsepower while maintaining excellent low-end response and drivability\u003c\/strong\u003e. Its 181° intake and 210° exhaust profile provides increased cam lift and optimized valve timing for a performance upgrade that works well in both street and performance-oriented Cummins applications.\u003c\/p\u003e\n\n\u003cp\u003eThe Stages 4 and 5 both build on the proven Colt Cams Stage 3 \"Big Stick\" profile with a \u003cstrong\u003elarger exhaust profile\u003c\/strong\u003e designed to improve exhaust flow.
