Is it an assumption?

What does "400" mean?

240, 260, 280, 300, 350, 370 all referred to engine displacement.

It'd be super cool if Nissan uses a VR40 engine, but I thought they are going to use the VR30?

What would be the precedent for Nissan suddenly not using engine displacement to name the new Z, and why is it called "400" and not "371" or "380" if Nissan just decided to use arbitrary numbers all of the sudden.

Pretty sure Nissan won't name the xxxZ based on xxxHP, I'm quite certain Nissan will use multiple states of tune on the VR engine to differentiate Z models....
