I don’t have one of these engines but figured it still might be useful to someone. The nice thing is I didn’t have to do much except change the picture of the engine block and rearrange some numbers! So if you have a Chevrolet LSX (LS1, LS2, to LS6, LS7) then this is the firing order you need to use. It’s nice as I don’t have to mess with a distributor for most of these engines, although I do think some may have come with them (NOT SURE, SEND MESSAGE IF YOU KNOW).

So if you want to cut and paste the Chevy LSX Firing order it is 1-8-7-2-6-5-4-3
