Does the 335 engine use any forged internals?

Does anyone know if the 335 makes use of any forged internal parts? I realize it probably doesn't but I'm curious given the power potential of the motor.

Crankshaft is forged steel on the 335 N54 vs cast iron on the 328 N52.

I just reread the engine sticky and didn't see anything about forged engine internals. sstarch1 had you seen something in particular in that thread? The only mention that I saw as about the steel crank.

Ah yes, I found it by searching the "2007 Engine Mechanical.pdf". Nice!

Crankshaft
The cast iron crankshaft is retained for the N52KP and N51. To accommodate the
increased power output of the N54, the crankshaft is forged steel.

I wonder why they only forged the crankshaft...?

Probably other things were strong enough as they were. What did you have in mind exactly?
