Shelby Question

[mike2]

In the 60's (when but a wee lad I was) my uncle took me to a race at Green Valley RaceWay, north of Dallas,TX. There was a sports car race going on that Sunday. The featured team and car that day was Carrol Shelby and the "King Cobra"
I was so taken by the Cobras that I have never forgotten that day.
I have since asked, cajoled and threatened people to tell me about the King Cobras. Nobody has been able to help me.
My question: Does anybody know of or remember the King Cobra. I have written Shelby with no response to date.
To the best of my recollection, it was a CanAm (type) car.
It was so much faster than the canam corvettes and others in the race that it lapped the field.
The car was magnificant as I remember it. If anybody has pictures of the car or know where I can find out about it please let me know.
