Speed isn't going to be your limiting (or breaking) factor, RPM will. Speed is just a byproduct of RPM x gear ratio. Exceeding the RPM limitations of your engine is going to be what damages it. The 3.73 gears will lower your top speed but accelerate quicker and have more power to push your truck to its (new) top speed with less effort.

However, for what reason does your truck need to be pushed to 100 mph? Also, at that speed, I would first worry about suspension, tires, and brakes being rated for those speeds, way before I worried about the engine.
