Road & Track, Here are the official 2015 Ford Mustang power and weight numbers

You get HP mostly in the heads through good flow and good cams so that means the intake has to match as well.
Jack Roush used to build us a 650hp mill from the 5.0 Cammer and it was all naturally aspirated.
Now, of course it was a race engine and it would have to be tune down a bit to be streetable and most importantly, reliable.
I believe it's possible to get 500/550 streetable horsies from the Coyote if someone was willing to engineer it.
The problem is, the market is more prone to boosting rather than getting most gains out of a NA set up.

In the vid, the modders also explained that theyw ere able to retain a good amount of low and mid RPM torque because of the TiVCT.
Since the S550 will have mid-phase long TiVCT, I am curious just how much more low and mid RPM torque can be gained.

I never said you said it was impossible. I only said it is possible and never tried to say that you said anything.
I remember your exact words were:
To a point, yes, for a given displacement, there is an absolute limit to what you can get out of it naturally aspirated no matter what you technology you throw at it. That is physics.
However, our 5.0 engines still have a whole lot more in them and are still a ways off from maximum tpossible torque production for their 302ci displacements.
The 5.0L is a great compromise between lower displacement V8 (actually, more a mid-displacement V8) producing decent torque and great BHP.
And the naturally aspirated Coyote isn't done yet; Ford still hasn't implemented direct injection. Will DI give more torque and BHP throughout all RPMs? Most likely, yes; especially if Ford can tune the DI spray patterns to work reliably, cleanly, and efficiently for 12:1 CR or more.
Even if DI doesn't give any more BHP than 435BHP or only adds a miniscule amount more of BHP, the area under most of torque curve will be increased, and also hopefully broadened. So that "pretty much limited to 400ft-lbf" limit is not true.
If rumors are true about a project "Voodoo," the GT350 will be producing in excess of what the Aluminator XS produces both in the torque and BHP departments while remaining naturally aspirated.
I remember your exact words were:
there are limits to what you can get from a naturally aspirated engine of a given displacement. Coyote is pretty much limited to about 400 lbf-ft without forced induction. making bigger hp numbers means they'd have to push the torque peak higher in the RPM band, at the cost of low- and mid-range performance.
