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:
well i am just wondering, i drive about 50 miles a day and I want something that can beat mustangs on the weekend. and there is no replacement for displacement, so i want a bigger motor. :thumb:
why not cam your 5.3?
I really dont know, I rather cam a 6.0:) . but we will see how money lays down, if I dont get my new job than it will be a cam. the motor in my current truck is starting to make some goofy noises sounds like ticking from in the engine, and a clicking noise from the valve covers, do you have any idea what might be wrong or are these noises pretty standard.
every LS based engine ive heard has some type of ticking even brand new one.
really, wow i didnt know that, my 2002 tahoe never made any noise. and my fathers yukon only makes noise whens it cold and he doesnt let it warm up. whats ticking.
Not sure what the tickings from, someone will chime in on that one. My sisters 06 ticks at idle so does mine.
well thats good to know, thank you. that saves me some time and worrying.
When the engine sets an open valve lifter will bleed down, then when you start the motor that rocker arms a little loose so it taps a little untill the lifter fills back up.
how long should the ticking last.
that sir would hurt your gas mileageQuote:

to the Op, my old 6litre with a 232/234 cam, 410s, 30" tire 3800 converter. i used to get 18mpg while cruising in the summer. thats with AC on
18 is not bad with those gears.
i dont live in a flat area either. I use cruise as much as i can to help save fuelQuote:

thats really surpising you got 18, i am at about 1800 -1900 at 70, and it is tough to push much more than 20.
also has to do with tune and how yoru fueling is setup in cruise modeQuote:
