6.0 or 6.4

[kingranch8411]

Well I had my 06 ford 6.0l stolen last Tuesday so I'm in the market again. Trying to decide whether to go with the 6.0 again or 6.4. I know the issues with the 6.0 but only know what I've read from 8 lug on the 6.4. Looking for some insight.

6.4 all the way

6.4 but I may be a bit biased. Both are good engines and both can have issues but I'm a firm believer that the 6.4 is much stronger.

6.4 only of you can DPF delete...

Once I start getting hassled... I'm moving to a 6.0 and bulletproofing and modding the crap outta it!

I've been in the same boat looking at the 6.4. I own a 6.0 too...I've seen several 6.4 guys on multiple forums complaining about the 6.4 mpg even when dpf deleted tuned etc etc. From what they say their towing mpg is what is really crappy and their previous 6.0 were much better. I think its a trade off..the 6.4 is great for the ultimate power but it's very thirsty. I like the interior much better too...for me I'm just not sure if it can justify worse mpg all around and would probably end up getting annoyed and selling it.

It depends on if you can get away with a dpf delete or not. If so go with a 6.4 all day! if not a 6.0 gets the nod.

I've had both and liked my 6.4 and it made killer power and was super nice inside, but the dpf, almost out of warranty, and super sensitive fuel system made me give it up. I was going to get a new truck but with all the epa crap with tuners and deletes and the fact that the 2013 6.7 PSD can not be tuned yet I said F the new truck and go back to a diesel I can play with.

6.0 PSD are a dime a dozen right now and there are some really good deals on them. So I picked one up and real happy with it. And the 6.0 gets better mileage then my 6.4 did with the same size lift and tires.

I forgot to mention the sensitivity of the fuel system good call. If you are travel cross country and hit a fuel station that might have contaminate fuel or get water in the system it will reek havoc and could end up costing tons of $$.

I wonder are common rail duramax and cummins sensitive to water in fuel the way the 6.4 is? Or do their CP3 pumps cope with it much better because better internals?

Every time I get into the 6.0 I think man I miss my 6.4. Stock to stock modified to modified there is no comparisson I think. You drive a 6.4 and you say thank you ford. Theres one thing the 6.0 is better at than the 6.4 and that is sound.

But the cheapness is a huge deal as well. I agree 6.0s are a dime a dozen right now and if your looking for cheap thats the way to go. If your looking for the better truck go 6.4 all the way its worth the extra money.
