I disagree with your statement that "Fords needs to work on the 7.3 some more".

Look at the 7.3 power curve and it says it all. With a big cube engine it should make its power very easy.

Ok. I made the comment regarding the power output per liter ratio. I think they could have done better.

Has some good discussion on the pros and cons of each engine, strictly from a performance perspective.

Looks like the 7.3 has more power down low, at sub-2000 rpm. Hard to beat displacement when it comes to the very low end power output - case in point, the GM/PSI 8.8 big block has nearly 500 lb-ft at 1000 rpm!

Which one works better in the long run, in terms of reliability and overall operating cost is yet to be seen. No doubt the L8T is a technologically more advanced engine.

Yeah, even though I am watching, I am sitting this one out for a while. I never consider a new platform until it has a couple years out i the market and any potential bugs have been worked out and such. I have owned both Fords and GM's. I am not specifically loyal to either brand. Whatever offers me the best value and most reliability at the time, along with features I need, that is where my dollars go.

Here's the power curve of the L8T and L96. Power softens under 2000 rpm. What's crazy? The 7.3 has nearly double the torque of the 6 liter L96 at 1000 rpm!

No... The goal was to design an engine that can handle heavy loads, while running as efficient as possible and be reliable long term while doing it.

In the long term, we will see if they got it right.

Please repost as I am unable to open whatever graph, chart, whatever you are talking about.

Yep... I'll place my bet on the big cube engine.

No bet. I do not place my trust in anything made by an automotive OEM nowadays. Learned quite quickly in the military that even the most elaborate vehicle or weapons system is made by the lowest bidder and can fail at the most inopportune time, so I have a certain cynicism built in to my psyche.. I really hope both Ford and GM have winners on their hands, as that would benefit all of us. But I have been around long enough to know that in today's manufacturing climate, caveat emptor.
