Designed to fill the gap between the tame yet high power producing 2.5 and wild high rpm stage 3 this cam fits the bill perfect. If you are looking for a little more lope at idle and a little more power than the stage 2.5, this is the cam for you. Still 100% streetable but you will give up some low rpm power for the rougher idle however not as much as the full stage 3 grind. Definitely Hot Street. RPM range 3200-7000rpm. Machine work to the valve guide bosses required with .550" tip length or factory multi groove valves. No machine work required with our valve, spring and retainer kit. Aftermarket springs recommended with minimum of 140# closed pressure.
