6.4 vs 6.0

I'm sure this horse has been beat to death, but I come from the world of 7.3! I have one question that can be answered with a simple yes and no. Extrapolation is fine, but a yes or no will do.

Is the 6.4 more reliable and less problematic than the 6.0?

This question is for a stock truck and just a general overall scope of everything type question.

Thanks friends,
Clint

Are you intending to keep the DPF system installed?

With all factory emissions gear on board, the 6.0L will outlast the 6.4L, and be more efficient doing it.

As the 6.0L was crippled by the EGR cooler (solved by aftermarket upgrades, maintaining functionality), the 6.4L's downfall is the DPF system, which robs power, fuel mileage, and longevity (as diesel dilutes the oil during the course of an oil change).

The 6.4L has more power on tap, other than that both trucks are basically the same from transmission back.

Another big area where the 6.0L is better, is the ability for the average guy to do his own troubleshooting and work, and not need the diagnostic equipment the 6.4L sometimes requires.

STOCK to STOCK the 6.4 will have less issues then the 6.0 (on average)

Until the DPF Blows up the 6.4 engine

They both need about $2-3k to make them great trucks but the 6.0's are more for people that are "do it yourselfers"

If they cost the same I would be in a 6.4..... But...... THEY DON'T.

So I love my 6oh. I take care of it and it returns the favor

deep down I love the 6.4 for the power... But IMO the price difference is not worth it and i'll stick to my 6.0 for now!

The 6.4 (so I heard) is a PAIN to work on with the cab on

There are guys that wrench on their 6.4Ls, however the 6.0L has fewer electrical sensors and processing that results in fewer troubleshooting efforts driving you in circles as you try to fix something that isn't mechanical and obvious.

If you are deleting the DPF, the 6.4L has a lot more potential than the 6.0L, however with either truck the transmission will need attention when you get around 500RWHP.

I'm a proponent of maintaining the factory emissions control equipment (not for the performance, but the possibility of fines, and legal issues), the laws are only going to get stricter. I can wrench and have my 6.0L nearly where I want it, so I won't be trading up any time soon.

I appreciate all responses. All i really plan on doing is deleting dpf amd getting tune to turn dpf off. No need for gobs of rwhp.

Found a decent deal on one....was gonna buy a 6.0......but this other truck seems pretty nice. Gonna go look at it tomorrow. Do the 08 still have factory warranty if under 100k??

It is a 2008 ccsb f250 fx4 lariat with 82k miles. $24995.
