With a V-8s power I seriously doubt you'll notice the difference. Someone said 4.56 gears would be ideal. For the trail, yes, but for a street/trail rig I'd go with 4.10s SO LONG AS YOU DONT INTEND TO GO TO A BIGGER TIRE LATER! If you plan on running 35s in the not too distant future with the same axles, 4.56 gears would work great.
