Ford 7.3 Gas motor

Straight from the Super Duty Order Guide ^^^^ are correct about 3.55/4.30 in 250 and 3.73/4.30 in the 350. Interestingly, the 6.2 is only available with 3.73/4.30. The 250 with 3.55 also has a lower tow rating than the 350 with 3.73. These lower ratios seemed to start in 2020 with the 10 speed transmission. Me thinks Ford is trying to improve their fuel mileage. It makes some sense that Ford would pick the 250 to try for better mileage since it has a derated GVWR.
