The 400 is 650 based, so nothing from the 300 will be in that engine. It’s also a lot heavier than the 300 engine. The 650 weight in at around 62kg which is a heavy lump, the Busa 1300 is only 58kg !!!

The press release said the motor is 1 kg lighter than the old 296cc motor so I struggle to see how it can be based on the heavier 650cc motor.
