As Patriot mentioned, I have had and still own a '94 454 Suburban with the Whipple supercharger that is totally stock except for Doug Thorley headers. I installed it when it had 50k miles on it and it now has over 102k miles on it and it runs better than new! No, I don't go out racing every weekend, but it is really nice to have the power when you need it for towing, passing, etc. I was one of the first to install the Whipple on my H2 (before Whipple had the solution for the torque management problem) so I had the pcm custom tuned by Ed Wright. He eliminated the T/M, raised shift points, firmness,etc. and it runs now like it should have from the factory. From my experience with s/c's, for a number of years, they will not effect the dependability of your stock engine if you are not constantly "putting your foot in it"! The only downside if you can call it that is that you have to run premium fuel with the s/c.
