Should be fine. If you run mid 11's at 115 mph then the engine will be spinning around 6500 rpm in the lights and the driveshaft maybe spinning at 6000 rpm. 6500 might be a little past your peak power point but it shouldn't hurt anything. You'll just have to play with it and see what it wants. The car might run better with 4.10 gears but no reason to make any changes until you gather some information.
