Would anyone have a list of color codes for purple shaft cams?

I'd like to see one too. I have a Purple Shaft for small block that I can't positively ID.

Gee, I've never had a Mopar Purple shaft cam, but don't the stamped numbers mean something?

For some reason the numbers on the cam were not the same as on the box it came in. Not sure why they did that. Most Mopar cams started with P4xxxxxx

An empty block, dial indicator, and degree wheel are your friend. Or just a dial caliper even.

I was thinking from a swap meet aspect. Guys always sell cams they have no idea of the true specs. Would be easy to identify.

Don't know about the colors, but here's a page of all the Mopar cam specs:

You really do need to check them. A cam from Gold(E)-bay, the highly ranked seller promoted it as a "slightly used" P4120235 (.484" lift) cam.
On vee blocks it indicated it at............. .2975"

No questions asked, the seller promptly apologized and paid return shipping.

Shouldn't you multiply that number by 1.5 or 1.6 depending on your rockers? .2975 measured lift isn't total lift. Would have been around .446 with stock rockers.

That's what he's saying. Not as advertised.
