LS swap 1st gen s10, what rear end should I use?

So, I have a 1991 1st generation s10, Put in a 5.3 LS and a 4L60E transmission in it. I am planning on eventually pushing 450-550 whp. I have a good bit of experience working on motors, but I don't know a whole lot about rear ends. So, my question is, What Rear end should I run to be able to have fun in the truck and not worry about blowing it?

Thank You!
