[Big hammer]

In a 4 stroke internal combustion engine the piston is at TDC twice, once on the END compression stoke and once at the end of exhaust stroke when the intake valve is opening. This is where your wrong, your 180 degrees out.

With all the spark plugs out, hand crank the motor and with your thumb over #1 spark plug hole you will feel or hear air coming out, this is the compression stroke, this is when the timing pin should drop pop in ! and this is when your points should open and fire the #1 spark plug, the rotor should be adjusted pointing to the #1 pin in the dizzy cap. Go back and look at the pictures posted, the correct picture and your wrong picture of the rotor.

In your picture showing the rotor I think I see the heat shroud around the rotor, is the bottom of your distributor open broken out ?
