I would recommend 4.56! I have an 02 with the 4 speed auto and part of me wishes I would`ve went to 4.56 even with the stock size tires. I went from 3.73 to 4.30 and it was a night and day difference it tows my 9200lb TT with no issues. With the 5 speed 4.30 would be good, 4.56 would be great.
BTW, is this an every day driver or Tow Vehicle only? That may make a difference on whether you go 4.30 or 4.56.
I would also recommend a custom towing tune from 5 Star Tuning. They are the go to tuner for Fords Triton powertrains, specifically the V-10 4 and 5 speed autos. the difference is truly amazing. between the gear change and the tuning it will turn your E350 into a towing monster!
And wherever you choose just make sure you do a lot of research on them. you want someone that has done them a lot. check out the reviews if available, or ask in depth questions, such as how they do it and what all do they replace?
