Jim;

OPs have touched upon the issue, but here it is explained (I hope) a bit more detailed:

If No 1 is at TDc the Rotor MUST of course point to the No 1 Station so that it can send the Spark there...but if it does not, it is likely likely pointing 180 Deg in the other direction (unless the Distributor Drive was changed), and it means that you are really at TDC of Cyl 6 (don't forget, its a 4 stroke engine, so Timing marks come around on Crankpulley TWICE for every single rotation of Distrib)...simply continue turning Crankshaft in the normal Direction of Rotation, one more rotation, until the Timing mark comes around again...THEN you will truly be at TDC No 1, and can proceed with Static Timing.

Good Hunting
