I believe it firing order is 1-4-2-3 (where cyclinder #1 is the closest to the fire wall) and your distributer has the plug wires running almost vertically.

1st cylinder = the very bottom
4th cylinder = second from the bottom
2nd cylinder = second from the top
3rd cylinder = the top connection on the distributer.

I hope this helps and good luck

I sincerely apologize for the late response...Due to the bad economic situation this site has had a substantial (+50%) increase in the number of questions being asked in the last four months.

I am not sure if you have the 1/2, 3/4 or 1-Ton model.
Also Not sure if you have the 4.3L, 5.0L, 5.7L or 7.0L Engine. However I have included all below.

For the 4.3L (6cylinders):
Firing Order:
1-6-5-4-3-2
Cylinders:
6------------5
4------------3
2------------1
(front of vehicle)
Distributor:

-----6------->............<--------5-------
-----4------->............<--------1-------
-----2------->............<--------3-------
............(front of vehicle)

For the 5.0L AND 5.7L AND 7.0L (8-cylinders):
Firing Order:
1-8-4-3-6-5-7-2
Cylinders:
8-----------7
6-----------5
4-----------3
2-----------1

Distributor:
