Seems to me they were rated at 19. And we all know they always rate them a little high, so I would expect 18.

I have 450hp at the flywheel with a 383 stroker in my 72. I think I have 3.55's. I turn about 3500rpm at 70MPH in fourth gear. This past summer I was getting 16mpg highway. I wouldn't be surprised at all if he was gettin 20+ highway in that 78 auto.
