i had 410s in my truck with 33s. IMO it could have used 456's for sure. but i was used to 410s and a 29" tire before that so...

Had 4.10s with 33s and it was right at 2200ish rpm in OD doing 60mph if I remember right. With the 35s its a little more sluggish, but still not too bad.

I would say 4.56s. I am going with 285/70-17's soon (32.7'') and will be going with 4.30 to keep my rpms under 2500 rpm (2470rpm to be exact) at 80mph since I do a lot of highway driving, and still be able to tow 5000lbs without to much downshifting on a slight incline.

just put 4.30s in my 5-speed with 33s. drives great so far (still breaking in so i ain't got on it yet).
my 4th/5th are almost the same as your 3rd/4th.
