Yep, right where the A or C or other letter is supposed to be is a big K, very plain and not smudged or anything.
When the wifey gets home with the digital camera I will attach a pic.
The only other marks on cam shaft are 5 Japan and E30.
It was in a wrecked 1981, 280ZX, nonturbo, auto trans, 2+2.
Thanks for the help.
