Looks good from here. Is that a picture off their website? Awfully professionally done for a garage photo.

Looks fine, at least the one in the photo. Could be some sort of lube/anti rust coating.

I think what you are looking at is the nitride treatment.

I think the lobes are usually parkerized or have some other kind of coating on them.

I didn't know they were nitriding the vintage pattern hydraulic cams now.

That just looks like a parkerized finish to me. I think the suppliers of purple shaft cams to mopar performance have changed several times over the years.

The good ones used to actually be purple between the lobes.
Ahhh those were the days...

I spy, with my little eye.... yup, that thar's a purpleshaft!
(This is in my current 440 in Fred. It's the 484 cam, as discovered back in 2017 when I did the swap).

The different manufacturers of cams have used a variety of surface finishes over the years. Prevent rust before install. Only new cams I had that that were a machined surface were my billet steel rollers.
