What should I expect going from the stock 33's to 35's in Duratrac or BFG KO2?
Not so much as far as mileage, but power.

Well with 3.92's and my mods (hemifever tune, S&B cai, MBRP cat back) my truck with 35's runs faster than my truck did stock. I can still pull a 6.34 0-60. I have the 35" duratracs and I love them!

3.21 won't be as peppy but shouldn't be a dog either

I have 315/70/17 Duratracs with a 2" level and I have 3.21s. It may have lost a tiny bit of power, but it's certainly no dog. The Hemi is a beast.

I have a 2005 5.7 and I'm running 35" tires with a 4.56s and I'm burning the tires from the start. I do a lot of tow hauling so I needed to do a rebuild because I burned them out when in I first got my lift and 35s. Still runs like a bat out of hell.
