G-bodies and S-10's have 2.73's. I had a 2.73 rear from a V8 Monza in my Opel GT. The upside, light car and I could get 32mpg. The down side, I had to red-line it in 2nd through the traps against the rev limiter. Shifting into 3rd made me slower.

The car only weighed 2100# with 330hp. It needed better gearing. A truck with more weight and less power will be not as stellar at acceleration.

I would not recommend anything less than a 3.08 with plenty of torque, or a 3:42 with an SBC and the trans you have.
