Assuming a rear tire diameter of 26.5" (approx. 295/R50-15), a 9" rear with 3.50 gearing and a toploader in 4th gear around 2650 RPM at 65 mph is about right. Swap in a close ratio T-5 with a 0.68 OD and drop it into 5th gear and now you are at 1750 RPM at 65 mph. That's the specs I got when I swapped trannies last year.
