Steve,

all else being equal i.e. same trap speed you won't be turning as high but you will get there a lot quicker and will probably pick up some mph so maybe you hit the traps closer to 6500. Let's not forget about converter slip... Good chance you'll trap near the same rpm's

If you're at 12.10 today I would expect something in the 11.7's maybe even 11.68. For your mph of 113, the car should be at 11.9's already and I would expect you'll pick up quite a bit more with the gear.

With the shorter gear, traction becomes more important so if you had any trouble hooking before it will be harder now.

Most of this is pure speculative bench racing with a few slightly educated guesses. Run it and tell us how it turns out!
