Rear axle ratio opinion

Thanks guys. I was just considering the stall of 3000 and the rear axle ratio whether the converter would be slipping too much at low speeds. No I do not race the car. I use it on the street and for cruising. I addressed this years ago and decided 3.23. But now I have the hi stall does it need the the lower gear? Also what do you mean 3.23 :1 is the optimal performance ratio?
