Any LowBuck but STRONG overdrive option?

AJ, I am OK with the trans ratio's as that is what I currently have with my non lock up 727. My current 727 is gett'n tired and as long as I have to replace it I figured that I would spend the money for a lock up 727 and converter.
442 HP, 340, 3000 stall, 3:55 ratio with 28 in tires.
With the lock up Im guessing the my engine rpm @ 60 mph will be around 2600 rpm.
Your thoughts?
Sorry to step on the thread.
