Loosen the clamp at the bottom of the distributor housing, rotate the housing so the connector points away from the engine, and retime the points to fire the #1 cylinder with the housing in its new position. You'll need to swap the plug wires around to coordinate the firing of #1 with the new rotor/cap relationship.

Get the #1 cylinder to top dead center of the compression stroke, (both valves closed) and give the housing about 1/2 turn to put the connector away from the engine. With the pointer and ball aligned in the hole back above the starter, rotate the distributor housing clockwise until the points close, then back up until they just barely open. Lock the distributor housing down in that position, and use whatever distributor cap tower the rotor aligns with as #1. Then follow clockwise with the other plug wires as 5-3-6-2-4. The engine should start and run from that point, and the timing can be tweaked as necessary for best performance.
