worse than i thought

I knew the donor car for my truck was a 77 Monte Carlo. I knew the rear end was a low numerical gear. 2.73 I assumed, but today I decided to check it. counting the rotations of each and it turns out to be 2.56. the truck runs great above 45 mph.while the width is great and it is in and working. I think a 3.31 3.42 would work better maybe even 3.08 I understand I can change the ratio if I buy a new carrier also. is this right? and has anyone done this? or are you just buying a rear with the ratio you want. the truck has a 283 mild cam and th350 so its not a hot rod.
