Not sure what you are looking for exactly; but, the firing order follows the sequence:
1,10,9,4,3,6,5,8,7,2 or what makes it easier for me to picture: 2,1,10,9,4,3,6,5,8,7 . In other words, front right, front left, rear right, rear left, etc....

Numbering schame: Left side: front to rear...1-3-5-7-9 and Right side front to rear 2-4-6-8-10

Here is a post that tries to explain the angle deal: http://forums.viperclub.org/2353911-post2.html

That is the extent of my knowledge on the subject.

Means it is a 90 deg block, but due to needing to fire all 10 banks in 720 deg (2 revolutions of the motor), they needed to get the pistoms firing at odd intervals - One at 90 deg, and the other at 54.

If they all fired at 90 deg, then they would have 900 deg total revolutions for all 10 to have fired. Does not work.

It's a V-10, four stroke. The engine math is a but strange if you're used to a V-8.

Does 1,10-9,4-3,6-5,8-7,2 mean the same as
1,10,9,4,3,6,5,8-7,2
or does it mean the 10 and 9 fire at the same time?
or at the same time every other revolution? (alternating a power and a waist spark))

Each piston fires once every 2 rotations, or 720 degrees.

In this scenario: 1, 10-9, 4-3, 6-5, 8-7, 2

comma = 90 degrees
dash = 54 degrees

Fire 1, rotate 90
Fire 10, rotate 54
Fire 9, rotate 90
Fire 4, rotate 54
Fire 3, rotate 90
Fire 6, rotate 54
Fire 5, rotate 90
Fire 8, rotate 54
Fire 7, rotate 90
Fire 2, rotate 54
----------------------
Tot. Degrees: 720

Thanks, that is what I was asking.
