3.54 @ 4000 rpm=94 mph
If I change to the 3.07 I get:
3.07 @ 2000 rpm=54.3 mph
3.07 @ 3000 rpm=81.4 mph
3.07 @ 4000 rpm=108.5 mph
I'm thinking I really shouldn't run the 283 at 3000 rpm to run at highway speeds of 60-70mph so I might go with the 3.07. What do you guys think?

xxxDid you look at the torque to the ground, we have to be careful and not end up with a truck that falls on its face, use 460 ft/lbs of torque to ground as a guide, much below that and the truck will not get out of its own way....look to keeping the gears you now have and changing out the transmission....what transmission do you now have ?
If you want to keep your current stock transmission you might want to go to 3:07,
if you want to change the transmission go with a t5 .76 ratio this way you would keep the same rear end and would have enough torque to pull it and cruise 63mph at 2000rpm......
