overflow size

Will a 1.5 inches overflow enough for a 1320 gallons per hour rate? My overflow is drilled at the side of the tank.

That´ll be a bit tight. Does the pump bring that much water at tank surface level or at zero water head? if the pump brings less at the tank surface it may just be enough.
