I've see that video and it was a small block, and from the sound of it , not running very well!
Besides, it looked staged to me. Everything filmed from the cobras angle to get a good shot of the supra winning!
The Cobra kept getting beat bad, and they would do it again & again, as if trying to get a 'convincing' take! Why would the Cobra keep comming back for more? I ain't bite'n!
I could beat a Cobra with a bicycle if the Cobra wanted me too!
