Mat,
You have me stumped too apart from two unlikely faults;
1 .Something bent or caught in the weight mechanism.
2 .If I remember correctly your MSD Dist has an inverted chevy type weight system which 'might' be installed for the wrong rotation, a long shot I know, but I struck it once before where someone fitted a marine dizzy to a car engine.-- lost a bit of hair over that one!
Another one is if the wires in the multi plug to the dizzy have been swapped this can cause the ignition to trigger off the trailing edge of the pickup and play havoc with the timing, think there is a page on the MSD website about that one, used to happen in racing where the teams were making up new weatherproof connectors.
Plus 40° total might be a bit on the high side.
