Mpg

I know these post are all over but i want a straight answer, i have a 5.3 CAI and exhaust, i am getting about 20 mpg on the freeway, what is a 6.0 swap going to do to my mileage?

It will go down a good bit. I would guess in the 17-18 range.

thats not to bad, not as bad as i would have thought.

i get 12 mpg.on a good day.lol

hummm, that sounds like it could cause some problems, what are you getting on the freeway.

14

but i am heavy as hell
AWD
and 4:10s

that could cause a drop, what do you think i will get with 3.73s and stock everything else.

shouldnt be that bad man.depends on the tire size too. but youll be alright

I will start posting some pictures when i go pick up the motor next month, thanks for the help.

if you are swapping a 6.0, why would you even be worried about mpg. you want good mpg, get 3.23s and 31 inch tires :laugh:
