Also, I may be mistaken (my memory is crap and grabbing the book would involve leaving the recliner) but it seems that the crankshaft should be turned 360° (which turns the camshaft 180°) from what's represented in the picture above before dropping the distributor in on the #1 firing position. The dots on the sprockets are aligned at 6 & 12 to make it easier to see that the cam and crank will play nice together.
