which rearend gears?

[Chevyguy]

My 90 Notch has the dreadfull 2.73's, I want to change them, but I drive over 80 miles each day on the highway. Everyone seems to love the 3.55's but would the 3.27's still work ok? or would there be very little MPG diff between the two? The 2.73's are so tall I cant run as much in 5'th compared to the stock 91 with 3.08's I used to have. 55 MPH is below 1500 rpm, no guts at all, 3rd goes over 100 MPH.

With even the cheap gas going near $2.00 a gallon, cant see going to the 3.73 or 4.10's
Maybe if I swap in a T-56, oh, was I dreaming again?
