Shelby doesn't build his cars for the drag strip, his cup of tea is more in the line of trans am type racing. If the
suspension and tires were set up for the strip, they would rip some numbers. As far as the road courses, yeah a vette may out ccorner it, but thats the curse of the pony car. The mustangs are in the camero, firebird, javilin and challenger class known as pony cars. To out corner a vette it would need a chassie like a vette, thats where the ford GT comes in or known as the GT-40 to us old timmers. The shelby mustangs, boss stangs and GT-40's won thier share of road races even against vettes and european sports cars. Even the 289 powered shelby GT 350's were awesome road racers. The mustang was designed to be a work car monday-friday and do well at the road course on saturday and win at the drag strip on saturday night. It does a great job of being all things to all people, but it can't be bullitproof at them all, but it pretty much is if you keep in in it's class of pony cars. The new shelby GT's may be better competetion for the vette's on the road course than the 500 as it has the lighter engine for better balance. I'm not an expert on the 500, I just know everyone seems to complain about the weight and I'm sure it maybe a little nose heavy, but also sure it would hold it's own in the pony car class. I haven't road raced one, but the one I road in was hell on wheels and seemed to handle verywell in the curves. The point being is the shelby 500 doesn't come from the factory as drag racing being it's primary task, set it up for the strip and you will have a straight line rocket.
