I need help with a 1965 Dodge Dart 270

Any idea where the oil leak is coming from? Valve cover, oil pan, etc? Was it a bad leak? Since its been sitting so long, it would be good to replace all the gaskets. Does it turn over?
I need to get a battery and test it out. I'll give it a shot this weekend and let you know the conclusion. I'll also post a pic of the oil catching rig my dad fixed up for it years ago. It ran from the hose connecting the air cleaner to the valve cover, into a coffee can and then back into the dipstick. My dad would give MacGuyver a run for his money.
