Want to change out my rear. Suggestions?

Well folks, It's that time again to change interest to a different area of the car which I have NO previous exoperience in.

I think one of my next mods might be to change out the rear.

What would you guys recommend as the most cost effective and performance balanced option? CHanging out the whole rear or just the differential?

Right now I've got I believe 3.23 gears and I know It's a peg leg. What kind of gains would I be looking at if I went to say 3.73's posi or even 4.11's?

Well, future plans don't include leaving this 305 anywhere near stock.
