Ford engines are numbered front to back - for the V engines, #1 is the front cylinder on the passenger side, #5 is the front cylinder on the driver side.
302 (5.0L) - 1-5-4-2-6-3-7-8
351 (5.8L) - 1-3-7-2-6-5-4-8 (also 5.0L HO, as I've heard)
300 (4.9L) - 1-5-3-6-2-4
My biggest problem has been landing one-off on the distributor cap.
For the V engines - the #1 cylinder 'should' be at about the 12 o'clock position, looking down at the cap from the front. My particular cap has a handy-dandy '1' molded in the cap at this location. Rotation is counter-clockwise.
Not sure where the 6-cylinder #1 cap location should be positioned. *edit* Rotation is clockwise.

Reason: added 6-cylinder rotation
