Any other gear ratios available????

My '84 3/4ton GMC suburban started out as a 6.2 diesel and has the 700R4 trans with a 4:10 rear axle(semi-floating). It now has a 454 with the 700R4 trans, I use it mainly for pulling a trailer, but it still has more gear then I need, what other ratios were available in this rear end? Was a 3:73 available or even lower/higher? Has anybody swapped and noticed a mileage or power difference??
