Single or Dual Pattern Cam

Back in the early 80s, Comp cams was a new company. They became popular very quickly, mostly due to some smart marketing IMO. I remember when the "Magnum" line came out, the ads said, " The 280 Magnum has a very racey idle in small blocks, mildly racey idle in big blocks. The 292 Magnum will make you the KING OF THE DRIVE-IN". Guess which cam I bought. LOL
