I hear your "Concern" in your post about my 8.75.. but there are plenty of guys running in the 9's on them and with me already having it I don't feel the need to change it until it's broke. This car will be 70-80% a street car anyways.. doubt I brake a 8,75 from light to light lol

If you're putting out that much power I'd put a Dana 60 in it. You can sell the 8.75 and all the parts for a good chunk of change. This will put a pretty big dent in the price of a Dana 60. If you grenade the 8.75 now you have to throw out even more money for the Dana vs getting the stronger rearend (plus the cost of having the driveshaft shorterned to fit the Dana) at about 60% of the cost.
I'd rather do it once vs doing it multiple times, but that just me.
