Here is a high level overview of the multiple generations of Direct Connection cams, as I know it, and I must admit some of what I know may only be partially true
but this is what I've gathered over time:

The very oldest that I know of were mostly Crane/Racer Brown/Isky, not even repackaged, sold at the dealer.

The first purple shafts had a vendor ID number, purple paint, and paint dots/blobs/slathers to halfheartedly attempt to identify them, and mostly fail to do so.
I hated trying to ID these, it was hopeless without measuring.

The next had a vendor ID, an internal vendor grind number, purple paint. If you have the decoder for the internal grind number you're good.

The next had a cam-only (not the packaged number with lifters) number engraved, purple paint was deleted...this change is very helpful for ID.

The very latest ones I have seen have the purple paint brought back + the engraved ID number for cam-only


What you have there is the second generation, the ones I hated trying to identify with the paint markings that were usually the wrong color or applied in the wrong place.
Best way I know is mock it up in a shortblock and measure lift and duration.
