Gearing?

[Big Blue Stroker]

Was wondering what gears i have... 97 F250 with 33s and at about 60 it is at 1600ish rpm wise. I think i have 3.55s. Also i am gonna do a dana 60 swap and was maybe gonna convert over to 4.10s and get 35s. First off is gear swapping easy and second off what would some one have rpm wise with 4.10s and 35s at about 60? Thanks

if you find a dana 60 with 4:10s(most have this) then you only have to change one set of gear in the rear and its not to bad, theres many write up for that axle on the internet or you can have a pro shop do it for relatively cheap. just gotta pay attention to bearing preload when swapping gears
