I know this is an old thread and I am newer to this forum, but not to the automotive world. I am curious about the theory behind the above quote. When looking at the two firing orders, it appears they just moved the load to the rear two cylinders instead of the front two (front crankpin journals to the rear crankpin journals)
Old FO= 1-5-4-2-6-3-7-8
H.O. FO= 1-3-7-2-6-5-4-8
this leads me to believe that it was more of a bean counter move to save on production costs.
