This is probably too late, but here it is.
Pull the distributor free from the engine to avoid damage, remove the number one spark plug, place your thumb over the spark plug hole and crank the engine, as soon as the compression blows your finger out of the plug hole stop cranking, repeat ubtil you get it exactly right this will be the compression stroke of number one cylinder, replace the distributor with the rotor pointing to the number one plug wire. your done; start the engine. PS: tighten the distributor hold down clamp this time!
