“1976 GMC Jimmy.

Currently building a camper van. 1979 G-30 1 ton 4X4. 350, turbo 350, Dana 60 rear, Dana 44 front, Warn locking hubs, front and rear power-lock diffs, 4-11 ratio, early gear to gear transaxle, all on 315 75 R 16s.

I have squeezed that Quuadrajet so tight I am getting 18 miles to the gallon highway at 65 mph. But... It is running so lean the bottom of the pistons are cooking the oil in half the time it would normally take. While that is excellent mileage for what it is, there is a limit to how lean you can run those. lol

Just got an overdrive trans to adapt into it. That should give me wiggle room to richen it back up a little and still get about the same mileage.
