Ford F-250 7.3 Gas Engine Axle Ratios
Is there much difference in towing milage, and around town/highway mileage with the new F-250 7.3 gas engine with rear gear options? Considering 3.55 or 4.30 axles ratios. Any input is helpful.

The original non turbo 7.3 was designed as such in 80s. The T444E, a replacement for the I6 DT360, to compete with the C5.9 for longevity etc. Which it did. The idi7.3 had a lifespan of 100k miles, as it was designed also to compete price wise with the gadmotors GM and For had. When international decided to scrap building using gas motors. There is only like 3 parts that are the same between to two 73 diesel variants.
The 6.9 and first 7.3 shared more common parts. Both initially were gas blocks. Put a different crank, heads, intake, you have the diesel version vs gas.
