XE282S in my 408??? Big enough or bigger?

I don't think the OP is asking if his cam is to radical for the street but should he step up in cam mainly for the lift to take advantage of his heads flowing at 275/200 at a peak of .600", I think if he was gonna step up it should be to a roller cam with about same duration with more lift. A couple of questions wouldn't .600" lift cut down on street life? And to the OP what Intake you running and is it ported to take advantage of your head flow or other wise a more lift might not do much?
