I have a T-5 with .72 overdrive behind a high pressure 235, with a limited slip 4.64 rear end, and 28 inch tall tires. It is wonderful for going as fast as I dare to go on the freeway and I can still pull out stumps with it. I believe that I could drag said pulled stump down the road at 65 MPH!
My next set of tires will be 31" tall which should dial me in to near perfect for what I need.
