A co-worker of mine purchased a 66 Skylark GS new back in the day. It apparently was a 2 dr, 400 ci, ST-300 trans, 3.90:1 posi, and heavy duty suspension. What apparently made this car special was the factory blueprinted 12:1 400 ci engine it came with. He claims it was one of 200 made, and it went like stink. Finding pump gas was pretty tough even back then, and he sold it within several years of buying it to settle down and have a family. He's been kicking himself for selling it for years now. Is this car really one of 200 made? What would be the value of this car now? There was apparently two of them at the dealership in Las Vegas when he bought it, and the other one was a 4 speed car.
