I am not sure what you mean by the "number one firing stroke" ?

If your timing marks line up on the cam and crank and the #8 lifter begins to spin as noted, what further is there to think about? The timing marks on the cam drive gears are not obligated to have any specific relationship to the position of the #1 crank throw. The actual lobes relative to the crank throw, yes, but the marks on the drive gears could be anywhere Packard found convenient. For example, they could have marked the drive gear 90 degrees off if they wished and then the driven gear would be marked 45 degrees off to match it.
