Priobe,
I have had 3:27 gears in my car since I built it in 1996 and I don't even have the BB. But I do have a 5 speed and with the .6 split I tac 1900 RPM at 70 on the highway. Even with the locker rear end, first and second gear are almost worthless when coming out of a turn as it just breaks loose. Your BB with the high torque would be even worse. At 60 MPH in 4th I tac 2525 RPM which has been verified by radar, so I am not turning the engine over real hard. If you are going to drag race, then lower gears definately. The only thing I would change in mine if I could keep it would be the split in the tranny. I would most likely go to the .8 split.
