Hello,
To provide some brief "History" towards your question hope this helps. "Mr. Carroll Shelby's involvement with the Dodge division of Chrysler Corporation began in the early eighties to breathe some life into an industry that had become at best, ho-hum. This relationship grew to produce the legendary Omni GLH and Shelby Charger and progressed into limited production full blown Shelby Dodge performance cars such as the Shelby GLHS and Shelby CSX, straight from
Shelby's Skunkworks in Whittier California. This relationship continued into the late eighties with more factory Shelby Dodges pioneering leading edge technology. The 1990's brought to life the Shelby influenced 1989 Viper Show car and the Dodge Shelby Can-Am spec racer." I pulled this from the FAQ's section of the SDAC website.
As far as the racing of these vehicles I believe they were entered in "IMSA Drivers Championships", SCCA racing events, and the IMSA GTU events (where the 1987 daytona shelby z I believe was entered in). In all of these races the cars faired quite well from what I have read.
Hope this helps out a bit to answer any questions you may have had. But back to Dan I hear ya, at least you have a "numbered car" as I have only the Shelby Z which I am always being told is not a true Shelby (though I like to think of it as). But heck I love it anyway and it is still fun to drive becasue it still carries Mr Shelbys genreal idea and philosphies.
Have a good one,
Brian
