new Ford 7.3 gas with 3.55 axle ratio, does it work?
Anyone have the new Ford 7.3 gas with 3.55 axle ratio? If so does it work out for a 2500# TC?

I would go with a 3.73. I had a Chev 2500 6.0 years 3.73 ago and pulled a 4000 lb boat all over the NW. The 7.3 will have a lot more power and also has a 10 speed transmission. I think the 3.73 will be much better mpg while the 4.30 will have more acceleration and use a higher gear.
