3:55 gears on the street

I am currently working to swap out the rear gears in my Duster with an 8 1/4 from a 2:76 to a 3:55. I have a 360 (bone stock) and a 904 tranny, 15"x8" rear wheels with a 255 60r set of rear tires. I want the car to be quick from light to light but still do 60 mph @ about 2600 rpm. Does anyone have experience with a similar swap? Any suggestions? I appreciate your feedback. Thanks!
