Are the cams changed in these kits? I have to wonder if they are not cammed aggressively enough above 6000 or so, these looks a lot like a head/cam setup on an early LS motor where the owner chooses big-flowing heads with a fairly mild cam for streetability. Big gains in the midrange but the slope of the curve tails off in the higher rpm. With VANOS a big cam's streetability seems less problematic? Looks like untapped potential to me, but I'm sure development would be off-the-charts expensive, and 8000+rpm means a bigger cam would probably need a revamped valvetrain to keep the weight down

Makes the S85 swap look kinda like an awesome idea...kinda
