Not Ranked
The 'new' Ford flat plane crank uses a lot of counterweight and places the rod journals in a one up/one down fashion along the length of the crank compared to Ferrari and others that have used- one up, two down, one up,- like a large inline four.
EDIT: with some help from people with more info than me I think I worked out the firing order for this engine, see attached dwg.
