Marty's numbers are a little off. The switch from a 3.64:1 diff to a 3.90:1 results in an ~7% drop in top end ie from ~108 mph to 101 mph. The change to a 5-speed O.D. (0.81:1) gives you about a 23% increase. The end result is a theoretical top speed of 124 mph. Theoretical because, unless you have increased your engine output, you'll never actually reach it.
