thinking about moving from 6.0 up to 6.4 or 6.7

[mtchockey30]

Hey guys my 05 f250 6.0 115xxx miles is getting a bad oil cooler and I have it in the shop now.. Its had a sct livewire on it for the last 4 months. I am going to fix it but am debating on buying something new and am stuck between the 6.4 and 6.7. Money is always an issue. I have heard that 6.4 gets horrible fuel millage?? Can that be changed with a tune and delete? If so what is that going to cost? Just looking for some help... Im without a truck right now and in a bit of a hurry to decide what to do. I also work at ford so I get a discount on buying new.. Thanks for the help

If I was between a 6.4 and 6.7 and money is always a issue Id go for the 6.4. Gonna be cheaper caus its older and its been around longer so a few less skeletons are left in the closet. You know what your gettin

Delete it and u should get decent mileage. It seems every 6.4 gets bad mileage unless delete. I'd go 6.4 it cheaper u can mod it and it is a nice engine if taken care of

Do you guys have any experience with the 6.4? Or is this just info from what u read. I have heard it is hard to come by and it is very expensive to do the delete and get a tuner. Im looking at a 2012 f250 lariat new right now for about $45-46000.. 5yr/100,000

If i may ask if you live anywhere of emissions tight states. If you do then get the 6.7. Now the 6
4 is an amazing motor with little flaws just as every motor has. If your going to keep it stock get the 6.7, but modded the 6.4

6.4 owner here. After all my research i did on here i chose it.. Deleted and mini maxx and egr delete. Truck runs like a striped ape. I've owned it for almost 35k miles tuned and its Ben a good one thus far. Thing pulls great. If u go that route get yourself an offroad tuner ASAP because they are becoming hard to find. Read up on that first. And like above stated if emissions are an issue for sure 6.7

my 2010 has been deleted for 30000 kms and has 65 on it know,not one single issue. you can bank on 18 20 mpg for sure. and to delete mine was 1200 for tuner and 150for delete pipe and 300 for intake. i would recommend the spartan as it is tougher to trace if warranty issues come up. if you find a low mile 09 or 10 delete it and you will save a pile over the 6.7. allso the two guys i know well with 11 6.7 are non stop in the shop with issues,just sensors but it leaves them in limp mode way to often don't know if it is corrected for 12 or not. just something to think about. and just my opinion but it looks like you want a newer truck but i have seen very low (25k) xlt super crew 4x4 for low 20k and to me thats a deal,but i wouldn't worry about the myths with the 6.4.
