We've Dyno'd that Cam extensively, forget the 'advertised' rpm range, it's all done by 5,500 rpm no matter the Stealth Heads/Intake makes no difference.... it's in the Cam and IMO, a complete waste of time revv'ing higher to go slower.
Which this is maybe a little off topic comment......
but just say'in
it's amazing how many people seem to subconsciously at least somewhat 'shop' or select a Cam based on it's advertised/published rpm range put out by the manufacturer ? And then believe erroneously that the Cam should rpm to that "advertised" upper number ?
FALSE !
Many Cams for example advertise a 3,000 to 6,500 rpm range..... all that means is that is "theory" and assuming everything within an absolutely perfect Engine dynamics scenario the Lobe profiles should remain "stable" to that upper rpm if the required V/Spring pressures etc are present.
NOWHERE does it mean that is where the particular Cam will make power to that upper number... let be BEST power.
I'm done.... morale of the story for anyone reading, do not select Cams based on 'published' rpm ranges.... let be try and Rev them there once installed.... which many tend to do subconsciously, and then in the Car anyway.
