Yesterday, I went to SBMO car show in Torrance H.S. with my '71 Mach 1 with 429 CJ, there's something I don't understand how I end up in 2nd place. Since my car is in '69-'73 fastback from factory stock, maybe some of you have seen a red '69 fastback with 428 engine, is that from the factory or modified? I was having a hard time to believe that it was from the factory since most if not all of his engine made of chrome and he won the 1st place. Not only that, but some do not belong to the factory stock. I know it was ballot by those who partipate the show but I need to understand how does this work between stock and modified?
