But i kinda wonder how you're going to put that much torque to the ground with a 9" tire and a car weighing almost 3500lbs.

I would but I think about a 29 to a 30in tall is all your going to be able to get without cutting your fender wells. For every inch you go up in height it will make about 5mph difference. So if you went to a 4:56 and was turning to many rpms you could always go up in tire height.
