Best was 9.3 going SE through Yellowstone on 287, worst was on PCH (route 1) at about 6.5 (constant hills and stop-and-go letting people pass).

Edit: 4.62 rear gears turning ~2,100 rpm at 65.
Porkchop,

Did your bus come stock with the 4.62 or did you change the carrier?

I do not know for a fact that it is 4.62 but judging by RPM at 65 and wheel diameter, I calculated it to be 4.62. I did not touch it, it came with it if it is in fact a 4.62.

By my calculation if you sixth gear is opened up it is .65 ratio overdrive and you have
11X22.5 tires with a diameter of 41.3 inches and your doing 65 miles per hour at
2100 rpm that would make the rear differential ratio 6.2 or there abouts. My bus has
5.38 differential ratio and 43 inch diameter tires 12X22.5 tires running only 5th gear
which is .75 ratio overdrive, at 2000 RPM I am doing 65 MPH.

Numerous other factors. Size of bus...gear ratios for trans & rear end...tire size...normally aspirated or turbocharged...intercooler (diesel only)...

That said...most any diesel will get better mpg than the 454. Anyone else care to chime in here?
