fireing order? 225 slant 6

Here's one you'll get a kick out of, I've made money betting on this one

Did you know that the popular Mopar / GM V8 18436572 is the same as the old Ford 289/302/352/390, etc, 15426378? It's because of course, that Ford numbers the cylinders on passenger side 1234 front to rear, and driver side 5678. If you draw it out, "cylinder for cylinder" they are the same firing order!!

(You have to overlap the orders, IE 1 Mopar is same as 5 Ford, so the Ford becomes 54263781, or if you go the other way and start with 1 Ford, 2 Mopar, it becomes 21843657)
