Since this cam utilizes ultra stable lobes, it will turn 7500 rpm with BTR's Platinum .660" lift springs (SK001/SP001). Also, using BTR's .685" lift springs (SP010-16) springs shimmed to 1.700" it can turn 8000 rpm.
Good lifters should be used like the Comp or Johnson short travel and stock rockers. Roller rockers will NOT turn as much RPM as the stock rockers will.
Most cam gurus claim .595" isn't enough lift for a nitrous cam, but back to back testing has shown otherwise, with increased exhaust lift showing no gains in power.
Cam specs are 251/266 .63X"/.595" 112+4
