I would do the following
1. get as much of the oil out as possible
2 add sea foam to the top of the cylinders and turn the engine over by hand (plugs out) this will help remove any oil left over and get into the rings.
3. put wd40 in the cylinders and turn the engine again. this will help lube the rings.
4. drop the oil pan and clean it out
5. replace oil pan refill oil do not forget to add about 1 qt in the distributor
6. try to start engine when running the engine use sea foam in the fuel.

now I would also add sea foam to the oil for the engine run. This will help clean out the crap in the engine, then drop the oil pan and replace the oil.
the reason the old oil will separate and glaze between the metal parts. the sea foam will help remove the oil oil in the areas you can not get to.
Good luck
