Theoretically a lower revving supercharged motor with more low end torque would be better. But Porsche does OK selling high end naturually aspirated screamers. Both are fun in their own way.
I don't aspire to a Z06. More power than I could use on the street and keep my license. I'm good enough on the track to use all that power, although maybe with practice.

Not to take anything away from the vette engine, but a ford TRUCK engine went 790 naturally aspirated. I have a F250 with this engine and it's a strong performer. Begs to be modded.. Engine design is doing some cool stuff. This achieved without 4 valve dohc, 5 throttle bodies and all done by 6500rpm. Ford is working backwards with a simplified engine that performs.

Interesting video. They said that the their test method adds about 70 HP compared to Ford using the SAE standard. But still, a lot of power.
I wonder why GM went DOHC instead of big displacement pushrod. A big pushrod motor can be more compact then a smaller displacement DOHC and perhaps lighter and less expensive. Fuel economy and emissions? Especially since GM’s truck engines are all pushrod
