I plan on rebuilding the advance on my 3406 this winter. I'll have pictures for you.
Part of the problem with copying the cat setup is just the sheer amount of force it would take to advance a P pump and have it not back off during the injection event when the advance is under significant load, then snapping forward to advance position, creating a long, slow injection that actually results in lesser performance than a non advance gear.
The stock P7100 drives much harder than most of the cat pumps. Start adding fast cams, big plungers, and big rpm and the force required to make a effective advance increases exponentially.
So at an idle will both pumps be timed the same?

No, one pump was at say 18 degrees at idle and the other pump would be at 30 degrees or more.
What is your injector setup going to be?
So, there would be two injection events?

First reasonable explanation I have seen on avoiding it. Thank you for that.

Are mechanical injectors going to react fast enough for multiple events given the two pumps on different time scenario?
Are the pumps going to have issues with overlapping events?
Any problems with one pump trying to back feed to the other?
Just being the devils advocate to keep the horse in front of the cart. Sometimes people jump past the small details.
I think you'd be better off with a common rail.I wonder sometimes if we would be better off with VVT
