Soon I'd like to change my rear-end to 3:73's for better fuel efficiency, and less wear-and-tear on the engine. Guy who had it before me raced sprint cars, and this was the pulling truck. Rebuilt 400 V8, rebuilt Turbo 400 and what I think are either 4:11 or 4:56 gears.
If you really wanted to go for fuel efficiency you could go grab a set of 3:08 gears. There are a ton out there, you could probably just go grab a whole rear end assembly from a similar truck at a junk yard. The nice thing about that is that rear-ends don't usually wear out, well not fast anyway.
