Change gear ratio on rear end?

Is it possible to change a rear end from one gear ratio to another?

If so, what is a recommended gear ratio for a Chevy BB 454 with around 400-450 HP, rebuilt and enforced TH350 with a converter at around 2200? The car is used 95% as a daily driver but as it is know is is not very a good idea to drive it on the highway (100 KPH at 3200RPM) and a pretty lousy gas milage of 3 liters/10 kilometers.

Today I have a 10 bolt rear end with a for the moment unknown gear ratio.

Thanks in advance!
