I've positively identified my 78 f250s engine as a 351w. It has the taller deck, so i know its a 351 windsor. I thought it was a 302 for about a year now, but i was wrong. I'm confused though!!! It runs on a 302 firing order!! Why is this? Does it have a 302 camshaft in it? Or is it possible for a 351W to run on a 302 firing order. I find this a little confusing. It seems to have a 351W electronic ignition distributer, because it has the large 2 piece cap. Can anyone explain what the heck is up with my motor?
