Why the 6.0L ?
I am curious as to why Ford changed to a 6.0L? Especially when the 7.3L was such a good performing engine, why fix it when it's not broke? I guess I know it as the saying goes "there's no replacement for displacement." What is done to the 6.0L that makes them that much more powerful and why can't it be done to the 7.3L and have an awesome motor? I'm assuming they are able to get better fuel mileage out of the 6.0L and a little less weight due to the smaller displacement. If anybody has any info, feel free to share. I'm just interested in the reason for the change. I guess my biggest problem with the 6.0L is that they are too quiet!! More noise means more power!!! 
Thanks guys!

The 6.0L now has 4 valves per cylinder, The injectors are solenoid on as well as off. It is also running a vari pitch turbo charger. They are able to produce torque alot quicker as well as being alot more quiet.

The EPA also is requiring smaller, more efficient, cleaner burning engines. The 6.0 is way different from the 7.3 in every aspect, about the only thing that stayed the same is they both run on diesel fuel. It's finally getting to be a good engine, now that Ford is getting the bugs worked out. With just a tuner and exhaust, these things will run away from just about anything out there.

I think Ford really screwed up on this one. The Duramax and the HO Cummins came out and (in MY opinion) they rushed to keep up at the expense of loyal Powerstrokers. I know there were some bugs with the first 7.3's but it should NOT be an epidemic like the 6.0's. I personally know of quite a few people that have gone Chevy or Dodge because of all the crap going on. My Dad just got the call yesterday that his new truck (350 PSD) came in and he picks it up this Thurs. I can't wait to see what it'll do but at the same time I'm about half scared....

Ford and International could have rebuilt parts of the 7.3 to make it a little more powerful and fuel efficient. The engine is already a PROVEN workhorse with quite a reputation behind it. Why start from scratch, cause yourself some serious problems, and lose loyal customers? If they wanted to, they could have come up with a way to put a 5-speed tranny (or even the Torqshift) and the 7.3 together. I (as well as many others) would have been singing the praises of Ford and International had they done it. Sure it would cost just a little more for some re-designing and re-engineering, but it would have been more than worth it. Especially when the time came to sell trucks equipped with it.

uhm guys,
noise does not equate power at all, especially in modern common rail diesels. And the reason why Ford brought out the new 6.0L, at least according to my info, is because they could not get the existing 7.3L to comply with the new upcoming emission laws of Californicate.
