E350 post Grocery getter re-gear or not

3.55 is very tall gears. I’d definitely consider 4.10’s and a trutrac, regardless of engine mods.

Agreed, the more I research the more I realize how wrong this stock gearing is

I have 305/68r18 tires and went from 3.73 to 4.10 gears. I am quite pleased. The ratio from stock tires/gear to the new ones remained unchanged. I am quite pleased with it. If you go to 4.10 your combined ratio will be shorter than mine, which may
a good thing if you do towing or mountain driving.

Check this calculator to compare your previous tire and gear with the new tires.

Yep, what I’m seeing is 3.93 would be for best MPG’s but 4.10 would be “best overall”
