Bob,
It would most likely have been Car Craft '81 or early 82...showing the Street Machine Nationals West at Devonshire Downs. Or was it the '79 Street Machine Nationals West? Can you check Car Craft for '79 for me when you get some time (Street Machine Nationals West)?
There's also a Super CHevy within 6 months of that that had a red 67 RS/SS 396 Convertible on the cover...I believe it was owned by a guy with the last name of King?
I appreciate anything that you can discover...
Like I said...don't worry about it now...you've got enought to worry about
