I have a 1934 chrysler coupe with a 1972 340 LA engine. Installed new D.U.I electronic distributor to solve a previous problem with dual points standard distributor. Engine ran, but missing and unable to find timing mark on harmonic. We are installing a new cam, so decided to investigate timing gears and found new double roller cloyes correctly installed and marks line up on TDC with cylinder 1 up. Last thought was to check distributor rotor position and found it to be 180 degrees off. I was amazed that the engine could run like this. Anyone had similar experience???? By the way, the engine did not run well and often died leaving it impossible to start.

Yes it will run like this because the cam turns once for every two turns of the crank. The spark plug wires must still installed so they still fire at the right time. If the engine has the wrong year damper for the timing cover (or the other way around) then the timing marks will be on the wrong side.

Just to save yourself a lot of confusion pull it apart and follow my setting up instructions here;

Check that the timing mark on the damper does reflect true TDC at the piston. Sometimes dampers go faulty and the outer part starts to twist around. Then they fly apart at speed and exit through the fender or hood.

Sounds like a cool car by the way. Wouldn't mind seeing a photo.
