Actually around these parts any Z06 with headers and a hot cam will roll away from a Murci until the Murci starts it's run up to it' top speed from 150 or so...
You do not find (at least I have never) a street driven Murci or Gallardo that is abused from a stand still - something about Lambo clutches and drive trains being notoriously weak and expensive to fix.
As for how a 650hp Mustang would treat a Murci up to about 140mph - I think the Lambo driver would be placing a cell phone to his dealer crying that a $20,000bucket of bolts just kicked his arse......
But as they say - it's not about "who wins the races"...
it's about "what the Murci represents"..
