What's the current axle ratio? A mild 402 with all that torque should work just fine with a 3.08 or even a 2.73, depending on tire height and desired highway speeds.
My 82 C10 had a mild 355/TH350 with a 2.73 and 29.5" tall tires. Cruising at 70mph was ez-peezy, but it would spin the tires in first gear.
Just trying to save you from OD expense and hassles, although the GV should be less of a PITA than a 700R4. And it will never break!
