Now I've driven both cars. Either the 00 Cobra R and 01 Z06, now I don't care about #'s because we all know that these magazines are bias. What I felt when I drove them was that the Cobra R would get up to speed faster than the Z06, and it also felt tighter when turning. I don't know the #'s for them right now but the R was better than the vette.

Stock, it will loose out at the drag strip and get demolished on a road course. If the Cobra owners mod, like smaller pulley to up boost, the car will easily outpower a stock Z06 but there is no point in getting into a 'mod war' as the Z06 owner will always win thanks to extra displacement, less weight and better aerodynamic properties. All it takes is a supercharger or turbos on the LS6 to put all mod arguments to rest.
With similar traction, if both cars are modded, you can't win with 1.1 liter less of displacement and 400 more pounds...
Both fun cars to drive though.

Well that's were you get wrong... displacement doesn't mean **** to engineers. Unless you're a hillbilly that still goes with the slogan "no replacement for displacement" and don't know any other ways of boost HP without increasing the engine size, displacement can be overrun by many things.
Let me just tell ya about F1 engines back in the 80's they had a small 1.5 liter V6 torbocharged that produced 1300-1500HP depending on team.
Now the Cobra engine has much more capacity of HP the LS6, just because this engine comes out with more HP it doesn't mean that's a better engine. The LT5 was a better engine than the LS6, it was heavier, but then again it didn't have any plastic intake. The fact that has more area of admission and exhaust to and from the cyl due to DOHC is a an advantage, well you might say well but OHV has better torque at low rpm's. Well then go buy a diesel.
BTW it's easier and cheaper to increase the displacement in the cobra than to install turbos or blowers in the Z06.
Now the fact that Ford used the a blower in that car ???? Maybe they want reliability. Another thing is, now that the blower is on it will be a piece of cake to get a hell of a lot of power from that engine, a few pulleys recalibrated injection and that's it'.
What I fear is many of wise guys with Z06's that know that the Cobra has 390 and they have 405, is that they are probably gona get burned because that car is gonna be a sleeper.
I don't like the Cobra what I like is their engine and that is no match, unless you have an LT5 (like me:d) and then you can bragg about a DOHC with more cubes than the cobra.
It's a shame they took it out of production. I imagine what it would be like to have a pair of turbos in it, and still be able to do 7000 rpms all day long. (not possible with LS6)
