Hanging out with other Ferrari owners... god no
Running from cops... yes
It's gotta be the *****. But you could buy so much more ***** than that for $200k. Ferrari is like a ***** subscription. Pay once, and hope you get your money's worth before it runs out.

A friend has a 360 spyder,(F-1) with the top down, it's literally instant viagra. Comes in handy with all the kittah that eyes us.

That url, as well as the countless many that I have seen fail to extrapolate the flow rates between .500 and .600 lift. It doesn't tell you what's happening at .550, .560.....etc.
With a stock LT4 head, I'd be looking for intake lift in the .540 to .550 range, and slightly higher lift on the exhaust side. But this is just my opinion.
