340 Engine Shake

The noise in the second video is severe. I seriously doubt that the engine is the cause. Something is not right almost sounds like a loose filwheel or clutch.
How does the clutch pedal feel? Does it make that noise in all gears? Find the cause of the noise and you will find the vibration issue.
So us some pic's of the spark plugs. Im old school and dont trust AFR meters to many variables.

Yes, the second video where the driveline is making a ton of noise is where this all started. It made that noise in all gears, except N. When I removed the driveline from the equation and installed a slip yoke. The noise went away and then led me to view the engine shaking, which causes the transmission to shake. Its more evident in the transmission shifter handle than anywhere.

Edit: clutch feels fine. No grinds, shifts in and out gear easy.
