V8 Firing Orders

[Lou Scannon]

Out of curiosity I have been "collecting" V8 firing orders. So far I have found 5 unique firing orders for a conventional 90 deg bank angle cruciform crank V8. For clarity, cylinder numbering is from the front of the engine to the back, so odds are on one bank, evens on the other.
They, along with their twins (cylinders numbered back to front), Ford numbering system equivalent, and a partial list of engines that use them are:

Original Twin Ford
12784563 15436872 15486372 Ford Flathead Lincoln Flathead Ford Y-block Lincoln OHV Buick Nailhead
18547236 14527638 18364527

Our 1911 Little Giant has conical valve springs.

Their reason may have been they did not know better in that day and age.

It may have been constraints with room.
