Since there are many camshafts that will work in either the LS1 or the LS2, I would be induced to conclude that the firing orders were the same for the C5 and C6 V-8 engines.

Don't know the C5 firing order but the C6 is 1, 8, 7, 2, 6, 5, 4, 3.
I must be getting senile, took me 45 Minutes to find the firing order. It's not in the owners manual and not in the index of the shop manual. I finally found it on page 6-422 Vol. 1 of the shop manual.
The shop manual is not user friendly.

And that firing order, handed down to Moses, sometime in late 1954, is the same one used in all small block Chevies since then. I almost tattooed them on my wrist during my first autoshop class in 1961.

In the beginning, I think Moses handed down 1-8-4-3-6-5-7-2 to the builders of the small block and told the to go forth and multiply... It wasn't untill the third comming of the small block that those numbers were revised...
