Sorry, wanted to catch this early. Mike, are you talking about the one-off Shelby GT500 or the Twin-Supercharged Cobra(s). If it was the Cobra (last post, I thought it was the 427-powered GT500), the Cosby Cobra was destroyed. This one, if it is the Cobra, must be the one owned by Carroll Shelby. It had a twin-supercharged 427 that supposedly produced 800 horsepower. This was linked to an automatic transmission. Supposedly, the car was capable of over 200 mph. Despite all of this, it is still worth nowhere near $5 million. It was just another small car with a big engine. You could probably build a very high quality Superformance with more naturally aspirated power for $200,000. All you need is a hot, maybe stroked, 429 with replica BOSS heads. I am sure that 900 horsepower (who needs that much anyway) naturally aspirated power can be reached using the stated configuration. Wow, that was a long rant. I am sorry again, but these things must be known boomsmile (I just can't stop using that).
