Yes, but now connected to proper manifold port. Thanks for the pics. You may recall during your visit that I have a running 56 400 that I have been using for reference while restoring the 55. The wiring order is correct, distributor orientation is the same. I have verified TDC and rotor positions are correct. With all this the RPM and timing mark on damper are unsteady. It is a puzzle.

For what it's Worth: when the engine was dissembled for rebuild (with less than 38,000 miles) number 7 piston had hole (burnt?) in the top compression ring grove. possible crossfire ?
