I already asked this question once, but is there a significant difference between a 3.50 ratio third member and a 3.25? I would go 3.50 but I'm afraid I could see driveability problems, excessive gas consumption and it being too aggressive for my engine. Any comments? The car will be daily driven and probably won't receive serious engine upgrades until at least next summer, but I'd like to get the car into the 14s by taking what I have below and adding a posi rear with some gears.
