Make sure the firing order is set right. These engines can run even if the firing order is messed up.
I can't remember which mark to use while checking the timing, but the mark is on the flywheel and you'll see the pointer sticking out of a hole on the passenger side of the bellhousing down by the starter.
If you haven't already, get yourself a shop manual and owners manual from one of the parts vendors. They are absolutely invaluable when working on these trucks.
Welcome to the Stovebolt site! Where are the all the pics you've taken?
Good luck, Jeff
