To not exceed a peak of 420 hp would require the torque to drop off steadily after 5000 rpm to only 315 ft lb at 7000 rpm along with a redline of 7000 rpm. Those simply do not seem like reasonable figures. If the engine makes torque and power curves anything like the M5 395 ft lb should make closer to 460 hp.
Where are you coming up with all this stuff? Are you pulling it out of your hat?

You need to put some substantive proof behind your "very likely" numbers because, if for no other reason, your conclusions conflict directly with what the moderator said and he has a direct line to the people who are making the car.
