I have a 216 with a 3 speed trans. Both are unrestored.
The truck will easily reach 65mph. A new clutch solved the 45 mph top speed issue and 30mph creep up hills.
Each cylinder holds 110 to 120 psi.
When you say plug number 3 is "wet", I assume you are talking about oil. I don't see where you identified the spinning pushrod as intake or exhaust. Oil is probably entering through worn valve guides. I suspect the valve with the wonky pushrod is not seating properly.
My opinion is you need a valve job at the very least.
