Right off KREs website, 80cc High Ports, puny 230 duration, .565 lift hyd roller, pump gas on a 463 made 580 horsepower. Thats a high lift RAIV cam for all intents and purposes.
No one can tell me a .264-.271, .750 lift sold roller will not make 600+ as easy as falling off a log.
You would actually have to try and not make 600 with a real cam.
The cam I am running right now, bought on a whim for 140$ would make over 600 HP. roughly .264-.271 .689 lift
