I have a 2004 Yukon 5.3. Am going to put a GT-45 turbo on it. I was thinking about 400-500hp because I did not want to swap in a 4L80e. Now I am thinking I will probably have to do that anyway, so I am wondering if the transfercase and the front and rear differentials can handle 600hp. this would not be dragged, or mudded, just driven to work with occasional romps on the gas. just thinking. what do you guys think?

Thanks
