Also keep in mind that HP has little to do with speed in an airplane. For take-off and climb, yes. But for speed, it takes a ton of HP increase to result in very little speed increase.
As far as the 2700 redline; a lot of that is because Lycoming has a very loose tolerance on balance. If you are going to regularly run above 2700, you should pay particular attention to balance. Other than that, many Lycomings are regularly run at 2800, 2900, 3000 rpm and more. Yes, it will shorten TBO, but not by as much as you might think.
