I hope to get about the same with my '82 Stepside with 304/AX-15/NP208 and 3.73 gears with 33" tires. I may have to change that ratio though. I only got 17 mpg with the same motor with switchpitch TH400/QT with 17% OD /3.73 gears and 33" tires before. It's the O/D that is throwing a question in about the final ratio.

If I could just figure out that EFI stuff, I'm sure another five mpg would be easy to achieve. Or if I would spend some time with that 2bbl carb..............
