Every single direct power comparison I have seen surprisingly shows little or no performance advantage for the 4-valve heads over the 3-valve heads, even well past 700 horsepower.
Even Kenne Bell can't take advantage of the 4-valve heads.
Like I said initially, the 4-Valve heads just don't pencil out...

The 3v is fine in forced inductions trim as you keep the revs lower, but in NA trim the 4v is really the only way to go to get those kind of numbers.

You keep mixing up stock with modified, street with competitive track racing and handling with drag racing. You've got your mind made up and you won't be swayed by reality. Like I said they already make the 1350 pound car you are striving for, just remember to bring your raincoat and goggles... 
I've added maybe 50lbs to my car, since I took weight out of the car before the supercharger. From the factory, the GT is 400 lbs lighter than a GT500. That's a ton of weight. I am more of a handling guy than a drag racing guy. The weight affects everything, including handling.
I know a guy that has tracked his personal GT500 and said it wasn't very fun due to heavy understeer at the limit. His exact words were that the front end was too heavy. This is coming from a guy who have extensive experience road racing Mustangs.
I know you won't believe it, but I built a GT500 beater in terms of handling. Any road race guy on this forum will tell you that the standard GT is a better platform for handling. Taking weight out of a car is hard and costs a lot of money.
If the 2011's weight with the 5.0L and 6 speed stays similar to what we see today. The disparity between the GT500 and GT will be closed. That's why Ford needs to take weight out of the GT500. Anyone that has a basic understanding of cars will welcome ANY weight reduction that Ford is willing to give us.
FYI, I will call any 3900 lbs sports car a porker across the board.

While I do agree with you that weight is the enemy on all performance aspects of a car performance. The spectrum includes handling, acceleration, braking as well as fuel economy. However no one ever said the GT500 was a sports car, it's a sports coupe..a GT. If someone was going to the hassle to race this car they could easily gut this car down to get it into the low 3200lb range..but you wouldn't want to drive it on the street.

If someone was going to race a S197, they are better off using a body-in-white or a stripper GT. You can get these cars down on these cars a bit (50-100 lbs) and still drive them on the street. Getting it down to 3200 lbs would be a challenge in the GT and nearly impossible in a GT500.

That's what's confusing. I agree that the GT500 is more of a GT, but Ford/SVT markets it as a sports car and it competes against sports cars in comparisons.

Here is a pretty good indicator of what we can expect from Ford's new 5.0L:
Jaguar just released specs on their new DI 5.0L V8:

The all-new 5.0-liter AJ-V8 Gen III engines – in 385bhp/380lb-ft of torque naturally aspirated

I've seen that. I am wondering how much of this engine developement was paid for by ford(much like most of Aston Martins awesome engines that have never touched a ford car), and then how much this shares with the ford 5.0? But the 385hp/380tq are with direct injection, so hopefully ford has something a little better coming.

Good article, if the upcoming Ford 5.0 has anything in common with this engine it sounds amazing!
"Unique, Jaguar sound quality
Sound quality is a key characteristic of all Jaguars and is one particular aspect that customers relish. With that in mind, Jaguar engineers have deliberately accentuated the acoustic feedback into the cabin in order to further increase driving pleasure."
So much for the people who said the new sound induction on the Mustang was "ricer".
BTW can anyone find weight stats in the article? I am assuming the acceleration would be fairly predictive of the 2011 if it is a similar weight.
