V8s have their place and the latest Shelby and Roush cars from Ford are running V6s if I read correctly.

The V8 has been marketed as the most powerful, fastest, and best for many years. I also fell for this until I started looking into diesels and it was my dad that showed me what power really was(1990 W250 4X4). I worked with diesels in the service and they were V6 Detroits in APCs and the V8s in the HMMV but that is a different type of usage. I do know a guy that bought a Ford with the 300 I6 rather than a 302 V8 due to the towing capability.

For Ford and GM to change to an I6 design would call for them to completely redesign their vehicles. If they have to do a cab off for a short length V8 think what would happen with a longer I6.

 

Yes dt466 same as dietroit 40

 

I am curious I wasn't aware that the fellows that put the 426 Hemi in the Dodge Charger for the 1966 model year were displaced AMC engineers. Would you care to shed more light on this?

 

Just that kind of narrow enginebays might be better by changing blockmaterial.

Check this article:

It includes an interesting comparison Al-CGI but have also some other information. The advantage CGI-greyiron it not that much, but some 10-20 % weightgains might be the result only in the block, and an overall shorter enging is making parts like the camchaft shorter, and lighter.

 

If i'm not mistaken, DT466 is actually the designation of the navistar/international 7.3L V8

 

Nope. The 7.3DI is a T444E. For some reason they don't use the D. And there are 2 7.3s, an IDI and a DI.

The 466 is an I6.

 

our ambulance service has all fords
our newest one (an 04) has a 6.0in it and we have had 3 turbos countless egr valves and coolers this one was junk from day one!!!!!!!!!
it has the rough idle problem like all the rest. if we start it every 3 hours it is no prob but what a pita now we are due for a new one and guess what ......... can't get anything but a 6.0

 

What?

The statement is perfectly valid unless you want to use "dates" or "facts" as evidence...

 

100% false

 

Why would you do that?

I read it on the internet, it has to be true!

 

Yeah man.

"Reality" has no place in "virtual reality"...

 

Not according to Furd, quote from their website:
"“The Super Duty program set the precedents for this new process,” said Davidson, “and the results have been nothing short of amazing. Our initial durability test vehicles exhibited near-zero issues in reference to powertrain.”

The focus of the program was to design a development process that more accurately reflected how Super Duty customers used their vehicles everyday. The team began by collecting real-world data from working Super Duty commercial customers, tracking their daily duty cycles.

The data was used to develop durability tests that were more representative of these real-world duty cycles. For example, this was the first time that dynamometer tests were run with the transmission bolted to the engine during the durability run, allowing engineers to see how the up-shifts and downshifts affected the powertrain during the duty cycle.

The tests were conducted using the most extreme and abusive conditions and run to five-times the life cycle that the hardest-working truck would ever experience, further assuring durability,

“By the time we launch this vehicle,” said Davidson, “the engine will have seen more than 10 million equivalent miles of testing both on the dyno and in test vehicles.”

The extended testing hours allowed the team to scrutinize every component and system under theses customer-driven conditions. As a result, more than 500 design improvements were made to the diesel powertrain to improve performance and durability. "

For Ford's sake, I sure hope that is accurate. Then again, I'm willing to bet that they said the exact same thing over the 6.0...

Does this mean they found 500 problems

thats the way I understand it ...there were therefore 500 shortcomings which they were able to identify and/or were aware of
