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.

When my timming marks line up side by side then No #8 tappet exhaust plunger is not in the position of loosening it self from the valve just after closing of the valve.
But when #8 exhaust valve and plunger just unmate from each other the cam gear mark shows 180` off from a side by side with the drive gear. As for #1 combustion stroke I was just noting where in position it was at.

I had to take time off again due my health, but I'm back on it now!
Ok here is What I'm getting; When the #8 exhaust valve just breaks from the tappet after completing it's exhaust cycle, I am left with the mark on the cam gear sitting in the 10 o'clock position.(looking up toward the fan blower direction) Rather than saying a 4 o'clock position to meet side by side with the crank timming mark.
