Camshaft operating rpm
Advancing or Retarding a Camshaft Summit is well worth checking and goes into details.
If the cam is retarded a few degrees normally it will make power higher. There are other factors like does the intake manifold help support the higher rpm range or work against it etc. Valve train has to support the higher rpm too etc.

Yes, as long as your valvetrain is stable. Different intake manifolds will shift the peak rpm higher or lower depending on the length of the runners.
Depending on how well it holds power passed peak rpm, you might not want to rev it any higher.

In general, as others have stated yes you can take a camshaft past its stated rpm range. You won't make more power necessarily but if you're trying to move out shift points or carry more rpm's into and through corners it can be of benefit. Just make sure your valvetrain and overall combo are up to the task of the rpm you're after. There are many factors that affect the operating range of a cam.

yes, agree. Also, op: Do you know the lsa of the cam in question? Tighter lsa cams usually have the ability to carry power farther past peak, than tighter lsa cams. This can be useful, as if you shift at 200-300 rpm past peak w/o dropping power (but realize you won't be making any additional power, either), it puts you that same 200-300 rpm higher in the next gear when shifted, which will help with 1/8 mile and 1/4 mile e.t. Hope this helps.......
WS6 Store High Lift 226/236 ASA cam in a 5.3 L33 pulls to 7,300 rpm is probably worth checking out if that's what you're wanting to do.
WS6 Store can help you pick parts and optimize for thst high rpm and probably more. Ideally you'll want an intake matched to support higher rpm.
