Expect similar street drive-ability characteristics of the stage 2.1, however this cam's powerband is shifted upwards slightly for increased top-end power (20+HP over 2.1). Expect power gains of 60hp over factory cams. Slightly noticeable idle change- doesn't sound stock but not lopey. This cam has been dynoed in more 400whp pump gas set ups than we can count- it's a proven performer and our most popular cam for our head builds. RPM range 2500-6500rpm. 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 125# closed pressure.
