it's only a 5.8 liter....smaller than the camaro's or the challengers engines....yet much more powerful. 
As much as I'm also a Mustang fanboy, we still have to keep it real.
Yeah well, you have to be objective about that, the 6.1 of the Camaro SS, nor the 6.4 of the Challenger SRT8 are supercharged.
Plus Ford as nothing to gloat about, there's still a couple of Euro/Nip with half the engine size that develop similar 6.1/6.4/5.0/5.4 power.
But you are right with the weight, I was off by a wooping 80lbs
... I forgot the 2012 shred 100 lbs with the new all aluminium engine. At any rate, despite Shelby's God like ego, and him stating he's making supercars rivaling Europe's finest, the 05-09 GT500 were a disaster. The 10 was a little power boost, a significantly improved handling ... yet couldn't really make it a wow car. 2012, still working on handeling. 3,820 lbs is still a freaking heavy car.
for track work. Sure you can impress your co workers with 'I have a gazillion HPs', but I'll take a Boss 302 over a GT500 to actually lower lap times. The Laguna Seca lap times are pretty self explanatory

)
As for the Shelby 1000
I can thing of many many many cars I'd rather drive/own for $200,000.
