Years ago I had a '69 Charger with a built 383 that did a best of 13mpg on a highway run, 8mpg was normal around town. I was younger and the environment was hardly a 'thing' back then. I've spent the last 25 years driving econo-cars, car-pooling, riding a bus, and riding a bike so I feel like I've made some amends. I'd like to do it a little more responsibly from the get go this time around.
I have a '68 Chevy C10 pickup with a 400SBC and Holley Pro-Jection EFI (<--- utter crap. Modern aftermarket EFI is much better). With my old 5-speed and 4.10 gears, I got 15mpg hwy consistently driving normally. I would think a mild 440 with EFI and a 5-speed should do 15mpg without much trouble.
