Those Magnums are pretty efficient. (the 318's anyway) 2 barrel or 4 barrel? Most times the 4 barrels will get a tick better mileage if you keep your foot out of it. All depending on carbs of course.
It had a 650 cfm AFB when I did the trip. It has a Quickfuel 600 vacuum secondary on it now, but I haven’t done a big trip like that since.
