Bro, you're talking about a 4.10 rear end in a car with over 800 horses and probably a stock tranny. While the info that fab posted is sound, you are going to have more than your highway rpm to worry about. You are going to have to feather that throttle like a motherfucker just to keep your tires from breaking loose. And while we are on that topic, what kind of tires do you have planned?
