I agree with Lenny5160. Converter lockup will change dramatically, It will slip more. Maybe try the 4.56 gear.

My thoughts too. Was getting suggestions from others that I would pick up alot but I'm not sold on it

Rpm=mph
That’s the short version

Hear lots of good things about the APD Max Speed....seems like better way to go if you don't mind changing to a different setup. There's another thread on throttle stops which got me doing some research.

That is a 12% change in gear ratio . not taking into account the probable loss of converter efficiency that will occur , that's a nearly 1000 rpm drop in trap rpm.
Not to mention the loss of reaction time and loss of acceleration coming off the stop.
I'd be talking to your converter guy , maybe looking at a lower stall higher efficiency converter using the existing gear.
You didn't mention what your trap RPM is . ....Is that a concern that it's too high ?
