Using sae 30 for oil. Not over heating, my electric fuel pump was kicking out due to switch opening for lower oil pressure in my 216. That is fixed. Time for a test drive. I have a weird vibration at high RPMs that I am trying to figure out...... Transmission assembly or engine issue is the question. I will rule it out and get a second set of eyes on it. Otherwise, she sounds great! Need to adjust valves (class would be great as long as I get to do it)
