288 stroke is 3 3/4 and the 327 is 4 1/4 inches. From one compression stroke stopped at TDC It has to make two complete revolutions for the next compression stroke to be at TDC. You cannot feel or place anything in the hole to indicate piston position because a valve is directly under the plug hole.

It can hard by yourself but after you make sure there can be no spark, remove the #1 plug, place your finger or a coin or maybe even a cork over the hole and crank or turn the engine clockwise as looking from the front until you start feeling pressure or the coin or cork is pushed or popped off. When that happens you know you are on compression and it is a matter of keep turning in the same direction until the timing marks indicate TDC.

Don't reverse direction when positioning for TDC because any wear in the timing chain or anything else will come into play. If that wear is enough then the dist will be off by a few degrees. When you are sure it is on compression and indicating TDC then look at the dist and do what is needed with wires or rotation to get #1 plug wire in the correct spot to fire at that position.

You don't need to have #1 in the hole where the book shows but you do need to keep the distributor body and position in the general area where the vacuum advance is shown or positioned. The connecting metal tube is stiff and not able to allow much flexibility of more than a few degrees as to where the advance can be positioned and still connect.
