Been keeping an eye on this thread since I'm wanting posi in my '71. I have a 350 with a 750 CFM Quadrajet carb, 3 speed on the column, and 3.08 final. While I was in the Army, on post I got around 8 to 12 MPG. I have a bit of a problem taking my time getting to the speed limit. On the highway when I was on leave going home and back, I was surprised to find I was averaging 25 MPG. I don't have a tach, so I can't tell you how wound up it was, but my average speed between home and post was around 75 MPH.
Hope this helps,
