Scuderia is 2976, according to the article I thoughtfully posted a link to.
Z06 is around 3179, while the base F430 is 3197. Sounds to me like the Z06 COULD have gotten there with the same formula.
It's sad that Chevy (the volume brand) thought that their supercar had to be as comfortable as possible. Ferrari figured if people are buying an expensive sports car like this, maybe they just want to go fast - not send grandma out to bingo...
