The gear is black, a cast gear is black, that is one of the topics Bob was trying to explain to me. Sometime he gets to talking and and it goes over my head.
Sleep well tonight
If I have time I will put to different ones side by side and post a pic.

You can clearly see the difference between the two cams.
Like Griff said earlier you are making something out of nothing.
I to was concerned like yourself, but I have two new engines at risk and will end up in divorce court if I mess it up

I thought you said that the 502 cam was a one piece cam, so the gear on mine and your cam is black in color? How is the cam steel and the gear cast? Basicly bob told me that if my cam has a pressed on cast gear that has been hardened then i also need a hardened gear in the distrib.
Anyone have the part numbers for the gm one in the base 502.

In case someone digs this up in the future.
Both cams are one piece.
one is a billet steel Roller the other Cast Steel flat tappet.
You can press a cast gear onto a billet steel cam to retain the original distributer gear used on a flat tappet cam.

Just a side note for anyone reading this. DO NOT put a dist. gear that has been run on one cam onto another cam, even if the cam is new. You are asking for trouble. Go ahead, ask me how I know. Once a gear has been run on a cam, it should not be used on another cam. Replace the gear with a new one. You can keep the gear with the old cam so if the cam ever gets reused, then you can reuse the dist gear.
In your case Ballon, you need gear # 10456413.

I would be scared to count how many cams I have changed and ran the same gear. I am surprised Bob M. never mentioned it, because that is the reason I wanted have always ordered cast gears to use the same gear on my old distr...
