LSM was one company I think a couple guys did them. There were a couple firing orders too if I recall correctly.
My cam was a double swap but, I think there were some that just swapped 7&4. It is easy to look at a cam and figure it out.
Just take a marker and mark the intake lobes. You can use a different color for the right and left banks to disrupt confusion. Then simply roll it across a flat surface counting off the firing order. There are only three possibilities.
18436572 18736542 18726543
After counting three intake events you should know which cam you have.

The firing order sway is basically making it a ford Windsor firing order. Tim

is this a power adder motor or N/A. how much separation do you need those ugl cams really limit your choice's.. 60 mm blank cores are not cheap I think comp gets 1000$ for a core but not sure. that is why I used a 55mm cam core.... 300$ core

My BB are 60mm custom from LSM I use a LS1 firing order, although I don't get them to grind them.

I am not going to argue this until I am blue in the face. Just no point.
Fords are offset backwards from bank to bank. How can you share a firing order with an engine that does not even have the cylinders in the same arrangement with each other?

Crankshaft loading is only part of why firing orders are selected as preference.
Sure a HO 302 Ford or mopar with a 7/4 3/2 swap will load the same crank throws at the same time but, I would hardly say from an engineering standpoint that one compares to the other. Maybe if you are strickly trying to engineer crankshaft load placement.
Intake manifold design and RPM is one of the reasons most engine builders I have talked to choose alternate firing orders.
None of this discussion has much to do with what the OP was asking.
