Re: Would you run this cam?
Small pits are fine on the journal as long as they are not sticking up.
The lobes look to be parkerized.
I would not run it until i found out what is up with the black color.
I would probably regrind it to something else and know what I had then.
Take a cloth and some lacquer thinner to it and see if the black comes off. Or carb cleaner.
