trade 6.4 for 6.7 does it make sense?

[08-450dually]

I've been contemplating the new 6.7 but don't know if it makes sense:

6.4 has navistar engine (will it be obsolete in the future?), major fuel guzzler, and not very shade tree friendly (cab off for repairs)

6.7 has ford engine, much better fuel mileage, no cab off for repairs.

My 08 only has 12,000 miles and is fully loaded with king ranch interior.
The 2011 is fully loaded too except has lariat, I prefer King Ranch.

Question: does it make sense to pay $17K difference to have the newer truck?

I know i can get better fuel mileage and horsepower/torque with modern tunes, but I don't think it will be as much (consistently) as the newer 6.7 from what i've been reading (fuel mileage).

The 6.4 body/equipment seems much more robust, heavier, industrial strength.

The 6.7 seems a little light-weight.......

decisions, decisions...
would love to hear your opinions

every engine will be obsolete one day.... and who knows the 6.7 could have its own bundle of problems since its the first round diesel engines built by ford since navistar. A 6.4 king rand with only 12,000 miles.... That truck isnt even broken in yet. Trust my get a down pipe, full 5" exhaust intake and spartan, you will fall in love all over again.

So... I say no its not worth it... plus IMO the 11's front end is butt ugly..

If you only have 12k miles on your truck I would keep it. Sounds like a really nice truck since it's a king ranch and all. Have you had any problems out of your truck? What Job is your truck? Plus you can get better mpg if you do a tuner and delete and making close to 500 hp or more at the wheels and 1000 tq or more at the wheels should be enough power for the common diesel owner. Plus if you do a lot of highway driving which it really doesn't sound like you do, you can get 20 plus mpg on the highway. Seriously I would keep your truck cause it is a heavier duty truck the '11 IMO. I mean how can a '11 350 have almost 2k more pound payload then a 450. That just doesn't make sense to me. I'm sure there is logical reasoning behind that but I wouldn't get rid of your truck. Plus you said you would down grade from a king ranch to a lariat. I just wouldn't do it.

I would keep the Truck you have, It is still new with very low miles, it does not make sense to trade, you can mod the 6.4 to run better and get better MPG'S also, the truck has plenty of life left in it. I like the new trucks but cannot justify paying the high prices they want for them. One day they may be obsolete but they will still have parts for them, Keep and Enjoy it!

Delete and tune it and you will have a new truck!

Just because Ford is no longer using Navistar doesn't mean that the engine is obsolete. Navistar is using the 6.4 for many other applications other then Ford.

Personally, I would keep the truck, as mentioned you haven't even gotten it broken in yet.

The 6.4l is alive and well. Its manufatured world wide as the Maxxforce 7 engine.
I wouldnt trade in my 6.4l for the new ford. Maybe in the future after Ive worn what I have out id consider it.

an f450 will never see 20mpg. so dont get your hopes up. the most i have heard is like 14 @60mph
