What should the idle RPM be?

At the moment, the car idles @ 550 RPM in drive. I can't remember if the number is listed on the hood. What should it be?

For some reason 750 keeps hanging in my head. Can anyone confirm or deny this?

I think it's supposed to be around 700-750... When setting idle, with the IAC disconnected, it should idle at 450 in drive.
