When comparing the firing orders, be sure you take the way the cylinders are numbered into consideration.

As an example the Ford "1-5-4-2-6-3-7-8" is (when looked at using Chevy cylinder numbering) is the same as Chevy: 1-8-4-3-6-5-7-2.

The Northstar, IIRC, has #1 on the left side looking at the "front" of the engine, driver side transversly.
