I put in the 4.10's and never looked back. He probably wouldn't feel much difference in pull going from 3.55 to 3.73.

 

From a guy who had 3.90's and then went to 4.10's...go with the 4.10's. There is not that big a difference in high RPM's between the two. But you can feel the pull difference. Don't waste you're time with the lower gears.
4.10's FTW!
