As you can see the trans ratio is very important, and probably why Ford doesn't offer a 3.73 or 4.10 in the 250/350 pickups anymore. They have chosen to do most of their gearing reduction in the trans.
Except that they do. 3.73 and 4.30 in the DRW. Or did you mean just in the SRW? Though you can get a gasser with those gears in a SRW.
Do you have the 3.73? If so what RPM are you turning at 75 mph?
If I'm supposed to have 18% taller gears than you in final drive, it sure doesn't show up on the mpg. You 6.7 guys are doing far better.
