Firing order?
Is this pic the correct firing order and wire routing for my 88 F150 302?
Does this also apply to our 89 F250 351w?
If these don't can somebody give me the pics of the firring order and such?
I found this on the internet so I don't know if it is correct but it says it is. I just want to verify it is.

^^^that. All 302s ran the 15 order except the HO which ran on the 13 order that was also run in the 351w HO. I believe at one point the 351 ran the 15 order and for changed it on all 351ws to the 13 order to apparently lighten the stress on the internals though I've never noticed a difference. My friends 1992 non HO 351 bronco ran the 13 and that was totally stock with 330k on it. Firing order is based on the cam you use, at least for carbed engines as I believe the ecu is programmed to use a certain one in later models. I have a 302 RV cam in a carbed 351 and it runs the 15 order.
