06 6.0 vs. 08 6.4 *discuss*

[LREhp]

Ok, so I currently have the truck in my signature.. 2006 F350 4x4, lwb,cc, auto.. Has 83k on it and I am just starting to have the symptoms of EGR/HG issues.. Which is ok, I have all the parts here to fix it...
BUT
I recently stumbled across 2- VERY clean 2008 F450's.. Both 6 speeds, 6.4's, 2wd, similar miles to my truck..
My question is this: Am I opening up a bigger can of worms getting a 6.4, or will I be in better shape?
I don't mind dealing with HG issues, EGR will be deleted, exhaust filter removed, small tow tune.. I take real good care of my trucks, I drive it 2-3 days a week and it tows our 32' tag race car trailer currently...
But I plan to get a 44-48' gooseneck soon, which is why I was looking for a 450..

So whats the consensus on these motors.. Please give me some info. Thanks!

you're ok with giving up 4WD?

[LREhp]

Yes and no, it will be my first ever 2wd truck. The idea is that this will become more of a dedicated tow rig and i will finish building my 79 350 cummins swap truck..

[strokinpower]

are you going to tune and delete the 6.4

[LREhp]

Yes, mild tow tune. Full turbo back, egr delete, looking too just make a reliable tow rig. Nothing crazy.

If your going with that big of a trailer I'd get the 6.4. It will tow better than the 6.0.

[LREhp]

I agree, thats why im interested to know what some of the inherent problems with the 6.4 are.

Your 6.0 is not even broken in yet. Honestly I think you'd be nuts to give it up.

The ford gold coolant breaking down and clogging everything up, radiators (on earlier trucks), and dpf problems are the most common issues.

Sinner- i agree. I love the truck, would only do it for a chance to upgrade. I follow the NMCA racing circuit, so i just want to have the best possible combo i can afford.
