318 runs real load and shakes like crazy

#5 and #7 sparkplug wires look reversed... Simple check to verify... Twice!
ALSO. At the 18 second mark of your video, the #1 ignition cable MIGHT be touching the twisted wires that control your distributor. This is a big no-no as this can induce a random, uncontrolled signal that can fire the ignition! Especially when using crappy old wires but, I understand that you are just getting things sorted and will improve this later. Set yourselves up safely to run the engine under total darkness and closely observe plug wires along their total length and cap. 4th of July may be over but, look a repeat performance underhood.
