The 3700 rpm redline is there for going downhill and using the engine to help brake the truck. When you look at dynos of this engine, the power really drops off after 3k, so you really have nothing to gain by running the engine at those speeds.
The engine should have no problem running at 2300 rpm. I would make sure to keep an eye on the coolant and make sure you test the coolant to make sure it is within Ford's spec's (nitrite levels and anti-cavitation additives) as the higher speeds mean faster running water pump.
