well i bought a set of 4.10s from rons machine on ebay and they whine like a 747 taking off and the guy that setup my rearend is going to get me a brand new set and was wondering how much of a differance is there from 4.56s over 4.10s as far as on the highway and as far as tire size

BlackGMC put a shift point calculator in the Drivetrain section that lets you put in your tire size and gear size ind and it tells you what RPM and speed you are at in each gear.
Since I just bumped from 4.11 to 4.30 i have to say you'll love it. Buy Motive gears.
I also switched to a taller tire so I didn't really gain hardly any rpm at 65
