By the sound of the new SRT-8 cars, they will be a handful for stock naturally aspirated Mustangs. Motor Trend supposedly just tested the new 300 SRT and it ran 13.2 @ 108 mph...with the autostick. Plus, the 300 SRT-8 is said to have a base MSRP price of just under $40,000. That means the SRT Magnum and SRT Charger will be cheaper and even a bit quicker.
