It depends on what the motor is in. The 302 HO in cars had the 351 firing order probably around '85 or so, I'm not really sure when Ford introduced the HO. In trucks, I think they changed the firing order on mass air 302's around '94 or '95, maybe on some speed density trucks too, I don't know.
Well some pieces might be different, but the piston positions are the same, so either cam firing order will work. You asked the question, and I answered it, then you tell me that it's wrong. I'm confused.
