TONS of mustang links on this page
Also at the above link was a SVT Cobra page in which I got the specs from called
Dean's Mustang Zone:SVT Performance
On the 94-95 Cobra I've seen the hp rating vary from 240-245 hp at various sites. The ONLY way I see how the 93 Cobra could have beat the 94-95 in 0-60 is because the 93 is lighter.
Steeda: I'd say on stock rubber about a 2.1-2.0 would be pretty good. As far as times on the new 99-up stangs, I don't really know. From what I've heard they are supposed to run around high 13's. Maybe get mid 13s depending on driver, race conditions, etc.
