Question about modding the LS3 and reliability

[FutureSSOwner]

Does anyone know how well the LS3 has performed in the past as far as reliability goes when you go in and add say an intake/headers/other boltons/good safe tune/ and a mildish cam? Maybe a 450-500whp setup?

What I would like to avoid is replacing major internal engine parts on fairly regular basis (not counting me doing something stupid). I plan on getting a M6 when the day comes so I expect the stock clutch won't last forever holding another 150ish more horsepower. Not worried about warranty of course, but just not wanting to own a daily driven headache.

I am new to the LS family of engines and I guess what I am trying to figure out is where in the past have the LS engines typically experienced the breaking points?

I suppose I am looking for some corvette owners experience with the LS3 but I assume that there are going to be some similarities carried over from the LS1-LS2 motors as well.
