375 - 380 at the crank should have been easily do-able.

Yeah, I know . . . as good as 380 or even 390 might have been, it still doesn't have quite the same 'ring' as "400". Not even if the ET difference was under a tenth and the mph difference about 1.x.

That would have been a piece of cake. My buddies 3v with similar Yote specifications makes 420 at the tires. It's no more high strung than a Yote.

There's a handful of highly-strung factory-produced N/A engines making over 120hp/liter and spinning to 9000rpm so the Coyote still has plenty of room yet with a "mere" 88hp/liter ('15+ version), and the Voodoo is still 100hp from the edge. The problem is that as you move closer to the edge, the development cost spirals upwards and the car becomes too expensive for most performance enthusiasts.
The Mustang is all about affordable performance for the masses so even though Ford is pushing the envelope further than ever, it's still having to compromise to keep development costs down.

Agreed. I was speaking more toward "real" cars.

In theory you could let Yamaha have at it and get a 5.0L making 800-1000hp..................At 13,000rpm!

Compatibility with conventional automatic transmissions will force some upper limit to how "high strung" Ford would ever be willing to push any engine intended for "general use".

Ford's 6R80 is rated at about 800590 lb-ft. The new 10 speed auto they developed with GM will surely handle more and is supposed to go in service soon.

They are currently working on 4.8 di motor to replace 5.0 said to make more power & better fuel economy .
