I'd say go with the ratio you already have and move on to other improvements if you use it regular at highway speeds - 2500 rpm for a good 261 shouldn't be a problem but 65mph with 55 year old steering and braking technology could easily be, not to mention the stress on wheel/axle bearings, these trucks weren't designed with modern freeways in mind
