The picture of CSX 3198 with Shelby was taken at Unique's open house many years ago before they went bankrupt. Unique was right down the street from Sam Pack and he took CSX 3198 and several other cars over for the show. Today Sam Pack's 427 (CSX 3198) and 289 (CSX 2109) Dragon Snakes reside in his museum with the 289 sitting behind the 427. CSX 3279 (Green Cobra) is sitting behind the 289 Dragon Snake.
Check out Sam Pack's museum (Cobra section) at the following link as there are a bunch of pics of the cars and information.
