How do I Rotate the Engine by Hand?

1968 Dodge Dart

I have my slant stripped down for restoration work. All of the accessories and the spark plugs have been removed. I can't see any way to use a tool to turn the engine. There are no bolt heads on the crankshaft pulley. I used my borescope to look for a socket drive purchase in the center of the crankshaft, but I did not see one. I grabbed the crankshaft pulley to attempt to turn it by hand, but was unable to rotate it.

How do you turn the engine manually?
