Purple Shaft Cam Specs??

I've got a Hydraulic flat tappet cam that was in my 340 when I bought it (installed by previous owner) and barely has any miles on it. Just trying to ID it so I can at least write it down on the box if I use it down the road or if I give it to a buddy or something.

In mocking it up in an assembled shortblock, I'm getting lobe lifts of .315" (int) and .313" (exh) which equals .473" and .470". That makes me think it's the 280/474 cam (P4452992), but the .050" durations I'm getting with my degree wheel are 232* intake and 234*. According to the victory library specs, the 280/474 cam should have @.050" duration of 238/238. For what it's worth, I measured a LSA of 110, so that seems to line up at least and all of the measurements I've taken are repeatable.

Has anyone degreed one of these Mopar cams? How close to published @.050" duration specs were the actual durations?
The 280 .474 will measure 234 @ 0.050”.

If you have time take a measurement at 0.006” and 0.008”. You’ll be surprised at those numbers too.
