I suppose I shouldn't be surprised because big cams are not known for economy, but still...

Since I got 8 to 15 mpg from a mild 383 with 3.23 gears, I figured 6 to 10 with this one.
Well, I'd like to get 10 mpg on the highway at a steady 60, since I already know it cruises nicely at 15-15.5 AFR there. We shall see wink
