1966 slant six 170 timing mark

Thanks for the info. I'd prefer to have one so I'll probably opt to put one in there. I'd this the timing mark I'm looking for? Top lip closest to the motor? Not sure if pic uploaded I keep getting an error message
No pic showing. I can get you a shot of mine tonight if you need it.
That would work. I still can't attach the photo for some reason. Thanks man
