No offence, but I know the 260hp Mustang GT does NOT compete with a 405hp Z06. It's a 1.5 second difference in the 1/4 mile.

The Mustang Cobra 390hp is much closer, but it must use a supercharger to get it there and it still get worse gas milage.

The reason I ask is because I've heard a couple of cobra owners complain their cobra is a little rough to drive especially in traffic. And plenty of them have mentioned only getting 5-10 mile per gallon. So, I figure if I put a modern high performance engine in my future Cobra then I would enjoy it as a daily driver a little more.
