Wow Ron - that would make your Cobra one of the quickest street Cobras out there!
What were you running under the hood of that thing buddy?
I have no way of getting a truly accurate measurement of my 0 - 60MPH time here but my Unique with about 500 HP & 450 ft/lbs torque, 3.54:1 rear gear and 2450lb weight stopwatches a tick over 4 seconds using the (probably inaccurate) speedometer. That's on 275 60 BFG tires at 27psi. The rock hard BFG's go up in smoke with the slightest encouragement, but they're the only tires that would last worth a damn on the roads down here.
