[Quik 64 1/2]

I was wondering what the average redline for a 289 is. As far as mods., I have full Edelbrock induction, cam dynamics cam (power range starts at 2800rpm) I'm not sure of the specs., headers, 2 1/2"exh., h pipe and 4:11 gears. Is there any way to extend the redline? What exactly determines the redline? Just curious but never really asked.
