"Quicker" advance curve; any benefit?

2.94 gears are giving it a hard time, I can tell it wants to rev up much quicker than it's able to due to the tall gears. I can currently hit almost 70 mph in first gear and third gear is useless for accelerating unless I'm on the freeway going 80 mph.
LOL. Yes I had a 3.08 rear geared car with 14" tires where the 1-2 shift was at 55 and 2-3 at 85. But with an 8.3 DCR at sea level, that made up for the lower gear fairly well. You're getting a double-whammy there...
