Couldn't agree more if you dont believe look up some peer reviewed research studies on it!

A good Tune Up the engine for sure using a wideband setup and monitor and depending on how much you romped on the engine when you drove it maybe complete a rebuild... I would definitely go with a stock 3.07 gear ratio or a 3.08 Richmond ring and pinion, and around a 30"to 31" tall tire in the rear even with a final drive of 1:1 on the tranny that will still get you down to some nice cruizing rpm's if you want to play around with different combinations go to
www.12bolt.com and go to the gearing calculator it is an easy to use excel file and allows you to put different tire sizes transmission and rear axle combinations and gives you a spreadsheet of everything you need to know. it is by far the easiest and best gearing calc I have ever used.
