Well according to this:

The rods are steel forged, here is the quote:
What makes the brand-new V8 engine powering the 'Stang so potent is how engineers were able to allow the engine to breathe. All-new heads sit atop an all-new aluminum block with cast-iron cylinder sleeves. The wide distance between the heads allows for the intake ports to sit vertically on top of the engine. The engine features four valves per cylinder and twin independent variable valve timing. Tuned stainless steel tubular exhaust headers eliminate the need for aftermarket headers to let the engine breath better. Inside the engine are a forged-steel full counterweight crankshaft and four-bolt main bearings and high-performance pistons and
forged steel connecting rods. Peak horsepower is reached at 6,500 rpm. Redline is 7,000 rpm.
Use of aluminum and composite materials in the engine lowered the V8's mass to just 430 lbs, some 20 percent lighter than the previous 5.0-liter engine.
I'm finding more too:

Valve diameter/lift (mm) Intake: 37/12; Exhaust: 31/11
Pistons Cast aluminum
Connecting rods Forged steel

"stout four-bolt main crank (that’s counterbalanced) spinning a set of forged rods."
Then I read about forged powder metal rods on 15 other sites.
So which is it and how does that affect us?
