The stage 2.1 cam was designed for excellent broad power without the expense of reduced drive-ability. Popular with daily drivers, road racing, and autocross this cam has a wide range of torque and power. It features excellent vacuum for power brakes, smooth idle and increased power output in the mid and upper rpm ranges (upwards of 40hp over factory cams) while retaining as much low rpm pre-boost power as possible. RPM range 2000-6000 rpm. Machine work to the valve guide bosses required with .550" tip length or factory multi groove valves. No machine work is required with our valve, spring and retainer kit. Aftermarket springs recommended with minimum of 125# closed pressure.
