Incomplete cam ID number, need help in I.D.ing

Somewhere here at the forum somebody had a list that I can not find on MP cam numbers. Below is a MP cam that lacks the last digit that could possibly decide if it is a 292/509 or a 284/.484. *I Think!*
But as we know, sometimes things get funny with MoPar numbering system.

Any positive cam ID help or cam listing would be highly appreciated.
