zrayr,

Feel free to give me a call. Advice is free. 502.759.1431 There are a ton of parameters and variables associated with horsepower, reliability, and longevity. Again, 5500 isn't a magic number....neither is 5000 or 6000. There's not really a set standard to what will live forever and what won't, but most engine builders have an excellent handle on what works and what poops the bed.
