340 wrong firing order?

So I duck under the hood and replace sone plugs, removing one wire and installing, so that I do not confuse my brain.

But I do by some reason remove two wires, and suddenly I don't know which is which. So I compare to 340 spark order picture. Suddenly, Im more confused.

1-8-4-3-6-5-7-2 it says in all pictures.

Of course, my order isnt anywhere near looking like that.

1-6-5-7-2-3-8-4 is where I end up if I start with cylinder 1.

Also, cylinder 1 isn't oriented at 6'o clock on the dist.cap either.

Problem is I know nothing of the innards of the engine. Only that it's a 340 (late 71 probably, it's painted blue), with 69 exhaust manifolds, qft slayer carb and an old edelbrock tm5 intake.
In 2014 the car did 285whp right after getting off the boat. Should I assume there are other mods done? May that be the reason for the spark order?

I'm becoming hesitant to drive the car...
