Car makers have targets when they are designing performance cars....

They don't slap together an engine and see how much power they can get from it and move on from there....

The C6 Z06 was first planned to produce 450BHP, as during its development that is what the Viper was making. It was planned to have a 6.4L 450BHP engine, then they changed that when the Viper was shown to have 500BHP to produce 500BHP. Yes 500BHP was their goal when they produced the C6 Z06, however that wasn't their only target for said engine. There was a price target set for the C6 Z06 as well (the car launched at $65,000 starting MSRP). The car also had fuel economy goals for it as well, so yes when they start a vehicle program that have targets and they try to hit all of their targets.

When the C7 was in development they were probably looking for about 450BHP, they were also looking at being able to get 30+MPG on the highway. The engine needed to have a certain amount of refinement and street-ability, so yes GM targeting 450-460BHP for the C7 isn't silly it is exactly how things work in the auto industry.

It is on internet forums and arm chair racers where it becomes a point of pride and dick measuring where we think that they have tried to get every ounce of power from their engine.

Notice that the Mercedes 6.2L engine isn't producing 100BHP/L or higher....... infact in some trim levels it produced less then 500BHP why? because that was their target for the program at the end of the day. This isn't actually just US automakers that produce low range engine in performance vehicles. Hell the Zonda use to pack a Mercedes sourced 7.3L DOHC V-12 engine that produced 550BHP.

The real big change here is Ford Voodoo engine as US automakers generally never aim for such high rpm engines since the 1960s.

Want more examples of this?

If you look through the 1990s and 2000s when Ford went with a SOHC/DOHC GMs OHV 2 valve engine produces more BHP/L why? because that is what their targets were. Not the BHP/L but power output and they were using a 5.7L engine. Ford example the 4.6L DOHC Cobra engine produce 320BHP (after recall) from 4.6L (or 70BHP/L) and the LS1 produced 305BHP from 5.7L (or 71BHP/L).

My point is that there are many factors in what these engines are producing not just one....
