[AT] Rationale for firing orders

[Larry D. Goss]

Uhh, yeah.  Make a diagram of the end view of a distributor -- nothing
fancy, just a circle with the numbers of the cylinders correctly labeled
in one of the firing orders for one direction of rotation (such as
1-3-4-2 clockwise).  Now start with number 1 and count in the opposite
direction.  Notice that you get the "other" firing order.  So if you
look at the firing order of both distributors as though they both turned
the same direction, it would appear that you had changed the firing
order by changing distributors.  But you didn't.  All you did was count
the firing order on one of the distributors in the wrong direction.

Honest, one distributor rotated CW and the other CCW. 
Seems like the Delco was CW but I'm only 50% sure. 
The distributor drive gear was different I think.  The
engines were the same block and rotation, different
front covers and crank flanges.
Thinking about it I can't remember if the 6 cyl
engines were the same way or not.  These would be in
Clark and White trucks as Yale 6 cyls used Chrysler
IND30's and later H225 slant sixes.
