This is about what I have got in my 2 n/a's over the years.
Best I have done is about 37 at 50 mph..
Once you get over 70 mph it drops a lot.
When new, i used to get about 35 at 60 mph in the 1980.

..I also have a 427 Cobra replica with an aluminum chassis.

My first trip in the Euro TD, I got about 30 mpg at 65 mph, with the AC going.
If we all limited our highway speed to 50, I'm sure 40 mpg wouldn't be too hard to reach.

Happy Motoring, Mark

Or at least a lock-up converter.

My 5-speed TD has the 3.46 rear.
With the 3.07 or 2.86 ratio the turbos use, that should provide some additional economy at highway speeds. But the automatics probably rob most of that.
Or there are alot of tired automatics out there.

Happy Motoring, Mark
