6.4 VS. 6.7

[fishnmachine]

I CURRENTLY HAVE A 2009 F-250 CC SHORT BED WITH THE 6.4 ENGINE. I WAS THINKING ABOUT TRADING IT IN TO GET THE NEW 6.7 ENGINE. I WOULD LIKE TO GET BETTER FUEL MILEAGE AND I HEARD THE 6.7 WAS BETTER. I WOULD LIKE YOUR INPUT TO HELP ME MAKE A DECISION ON IF I SHOULD TRADE IN THE 6.4 FOR THE 6.7. I WAS ALSO WONDERING WHAT THE BEST GEAR RATIO FOR THE REAR END IN THE 6.7 WOULD BE THE BEST FOR FUEL MILAGE BUT ALSO GOOD FOR TOWING.

Is your 6.4 tuned/deleted? The 6.4s get decent milage once you delete the dpf.

I'd stick with the 6.4 for now. Wait until the 6.7 has some better tuning and starts putting down some serious numbers before you jump ship on the 6.4...oh yeah, stop shouting!

I love this 6.7L

What numbers are you getting with your 6.4? I went from a head cracked 6.0 to an awesome 6.7! Unless you make a huge jump in engines like I did I wouldn't recommend upgrading just yet. I drive both my 6.7 and a 6.4 at work, not much of a difference although my 6.7 tows like a dream while the 6.4 hauls like a dead dog.
If you're into trading up to keep a warranty, go for the 6.7. Depending on your mileage now, I'm getting 16.7mpg highway with just a CAI, and whether you want to tune and DPF delete, it's basically personal preference.

The 6.7 is a lot more refined than the 6.4. It's road manners are way better. It drives and rides a lot better than a 6.4. I also like how Ford offers an extended service plan on the new trucks. Believe this program rolled out in 2012. You basically pay for a maintenance package upfront and then you get "free" maintenance for however long you bought the ESP package for. Stock for stock, the 6.7 will get better fuel mileage. However, it will take a lot of driving/fuel to pay for the difference in price between the 6.4 and the 6.7. If you like all the toys and bells and whistles, the 6.7's interior has a nice EVIC display.

just throwing my 2 cents in i went from 2010 f-150 last year of the 5.4 to the 6.7 and let me tell u i do just as well in fuel mileage plus i love the power it makes me smile every time i drive it. I don't know much about the 6.4 never heard great things on it but a lot of guys love to throw down with the new motor ford made

I would personally hold off until next spring.
First, the deleted 6.4L is a better engine in every way possible, but they do not make it anymore. It's history. Nuff said there.

The 13' MY run is a short one, and one that will end next June as the 14'MY will start building in July. Order banks open in March.
With Ram stepping up power and interior, and GM launching a next gen truck, I suspect there are big changes coming in a few short months. I'm ordering a 14' as soon as I can.

My 6.4 is currently stock. Should I get the spartan system and delete the dpf. I pulled a heavy landscape trailer the other day and it felt like a dog towing it. I had a 6.0 that towed great. I had the banks big hoss bundle on that truck. I never had any problems with it. I think I might test drive the 6.7 to see the difference. I average 12 mpg with the 6.4.

Spartan or hs you can't go wrong. Do some reading on both to see which one will fit your needs best.
