4.10 or 4.56 with 400 turbo.

Our car is a 71 nova 3400lb with 32x14.00x15.00 tire it is a bbc 505ci with about 350 to 400hp nos.9.5inch torque convertor.Mostley racing 1/8th mile.We have run it with 4.10 gears and it has run 122.73.But its only going through the traps at about 6000.Would like to go through about 7000 to 7500.It only had a 1.46 60ft on that pass and still ran a 5.92 at 122.73mph.So was just wondering if a 4.56 or even a 4.86 would pick us up or hurt us??

If the car was not spinning, more gear certainly won't hurt it. I would likely go with the 4.56.
