NOTE: the OP was asking about COPO and/or Yenko first gen Camaros. As I stated, when the sYc logo appeared I always saw "Yenko Super Car" referenced, once again as it pertains to 1st gen. Camaros. Also loosely Yenko Super Camaro, or Yenko Super Chevelle, until that pesky Nova came along, had to call it Super Car or change the logo!
Lynn maybe you should contact the folks at wikipedia:
https://en.wikipedia.org/wiki/Don_Yenko
"This limited series of cars sometimes began to take the name
"sYc" (standing for Yenko Super Car), after the graphics found on the hoods and seat rests."
https://en.wikipedia.org/wiki/Yenko_Camaro
"Yenko rounded out the visual package with front and rear spoilers, a cowl-induction hood, special "Yenko 427" badges, twin stripes down the flanks and hood, (not with all cars however), and the
sYc (Yenko Super Car) badge, (again, not with all cars)"
