What is the max hp rating for the 05 Mustang gt 8.8 Rear end.... and is it possible to modify it to handle around 650rwhp or do I have to buy a crate rear end?

I wouldnt push more than 400 hp to the rear wheels w/ a stock rear end.The 8.8 is an excellent rear end,and when its setup right,it can easily handle 600-700 hp.Companies like Moser,Eaton,Strange engineering all make excellent pieces for the 8.8,all the way from ring and pinion sets to 31 spline axles to complete rear ends.Google these companies ans see what they have to offer.
