Even though Bernie indicated only CSX in title, I've been including COB prefixed Cobras. With only just over 1000 all up including COB/COX prefixed cars, I thought we wouldn't get many cars if we just listed CSX prefixed ones. And I think most people appreciate COB prefixed cars.
Snaken, will have to see if you can find out the chassis number of that big block. It could be a COB, I've read somewhere that they did produce a few big block cars with COB prefix.
Ralph, SACC only car about Shelby cars, so only track CSX prefixed cars. They do track the new CSX labelled cars.
