COMP Cams offers HV camshafts for a variety of objectives—such as drivability, towing, greater throttle response, moving peak torque to higher RPM in smaller displacement engines, and more. The cams deliver awesome performance gains (up to +94 hp), as well as increased torque across much of the operating range. They provide a deep rumble and mild, yet noticeable lope. Depending on your vehicle, HV cams are a great choice for engine swaps in full-size cruisers and daily drivers, including heavier vehicles (trucks/SUVs). Order the model recommended for your year/make and engine application.
