Ring and pinion for 402 BBC

[toddrh1]

Guys, I have about a hundred miles on my truck since installing my mild built 402 big block, th400, and 3.08 rear end. I've noticed a nice hum from the rear end so I'm going to install a new ring and pinion. My question is for anyone running 3.42's, how do you like it? My truck will never be a daily driver and probably not spent too much time on the freeway. With my 275/55/18 rear tires I'm looking at 2132 rpm at 60 mph with the 3.08's and 2368 rpm at 60 mph with the 3.42's. Any thoughts? Thanks.
