distributor gear is locked up with cam gear

Try to hand turn the engine back and fourth to see if you can free it up. If you feel to much resistance dont force it, never force anything on an engine. Take the spark plugs out to make it easier to hand turn. As you hand turn it over, have someone gently pull up on the dizzy to see if you can free it. The crank pulley nut is a 15/16 socket i believe.
