Numbers on an MP cam will likely be no help. Measure a lobe.

I am pretty sure I can ID that one if you can hang on until I dig my decoder sheet out of the basement file.
They changed over time.
Oldest: Very oldest, Isky and Racer brown stuff....Oldest DC was paint dots-good luck...measure....
Middle: Internal cam grinder number-need to check the top secret decoder ring, that's what is shown in the pic, why they did this I have no idea....
Later: Around 2012-2013 timeframe...Cam-only engraved number (doesn't match fully packaged part number but is usually close, and is on the I sheet), but without the purple paint
Latest that I know of: cam-only engraved number (doesn't match part number but is close, and is on the I sheet), WITH purple paint
Off the top of my head, I think it is probably a 280/.474/110.
But that is just from memory so might want to hang on and give me a chance to look.

Finally made it to the basement file to check.
Grind number 111031 corresponds to cam P4120236.
This cam was used inside packaged kit marketed as P4120237.
This is the ubiquitous 292/.509/108 B/RB Wedge single bolt camshaft.
You've got yourself a .509. everyone's favorite! (???)
Thank you for calling Direct Connection,.and have a great day

Who knows what Direct Connection / Mopar Performance secrets remain buried in someone's basement? The Z-man does!  A Gentleman never tells  Only recently have I begun to focus a little bit and it's starting to pay off. Can you post the list , I have a few unknown Purple cams lying around, Thanks! I can't, I don't have it in electronic format anymore that I can recall. Just on paper. It would take several hours to enter all that data.
