Meh.
Its hard to argue with results. Fox Mustangs are the ultimate street strip cars. They come with a decent four link suspension, disk brakes in the front, strong rear end, five speed, efi, roller cams, etc. They run low 14s, high 13s bone stock, and get 25 mpg doing it. The aftermarket supply of parts is second to none. With smart upgrades it is totally possible to build an 11 or 10 second car that you can drive to work every day. Oh, and the headers are easy to put on.
All that said, they are everywhere. I've had a bunch of them, but always end up getting rid of them because they're more like a drag racing appliance than a car.
That said, if you're bucks down and want to run 12s or 11s, you're not going to get there in a Mopar.
The car in your sig isn't a 72 Dart??
