Gear recommendation

I have heard for years that you go up a ratio or two like you posted. Never understood why, since if you have the optimum rear ratio for your combo, you would now be revved too high with the lower ratio.
In my super stock car, I switched from a 2.52 low gear T350 to a 1.96 powerglide. Neither trans had all the whistles and bells, but were decent pieces. I ran virtually the same.
Going from a T400 to PG, I would've be surprised if you ran quicker just based on the efficiency of the 2 transmissions.
