V6 Engines Originally Equipped with Flat Tappet Cam. Works with Stock Computer/Fuel Injection. Good Low End Torque and Gas Mileage. Magnum camshafts are very aggressive and specifically designed for the street enthusiast looking for more power with that Pro Street sound. The hydraulic roller cams do dramatically decrease friction, as well as lifter wear. As far as power, the roller profile allows the design of more lift, and a greater area under the curve giving much better top end power without sacrificing bottom end. You will notice a racey idle with the 280-grind while the 292 and 305-grinds will produce a rough or ''rumbly'' idle. Stock components are incompatible. Changes are needed in rear end gear ratios, headers and the torque converter.
