The difference will be bigger than you think. You will be in each gear longer before shifting, will hurt acceleration and mileage. I run 2.94 in many cars, but the 2.76 in small engine hurts the drivability and fuel mileage.
Tell us about you and your car, what's been done to the engine for more power? How do you drive it? Freeway, around town, any hills or is it flat there. What size rear tires are on it?
Remember riding a 10 speed bike. Starting out in 8-10th gear is hard to get it moving compared to 2nd gear. Same power & weight, same machine, different gearing
I bought a 4000lb car with a 440+6, 2500 converter amd 2.76. It was not good from a stop, rpm high and working engine to get it going. Then changed to 3.23 and it drives out easily and converter doesn't flash up so high to move the car.
