I too have a cam out of a 528 crate motor that I do not know what the specs are. I know it is a hyd cam as I have all the lifters and im the one who took it out of the motor. I wish I could find the mopar specs they had for this cam and compare to what my findings are.

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.

Gary, the pre-Barton one was 248/252-108 .524/.543 according to old marketing materials.
The Barton one was a departure from traditional direct connection marketing and deliberately listed no specs.
I'll definitely be back for another chassis Dyno session one of these days.
