Re: EFI years
I'm going by a lot of Bronco websites, with histories, I've surfed that say the 351 got EFI after the 302. Also I was sure the 85 302s were all carbed until someone set me straight that they had an EFI 85. But like I said earlier, I'm new to Ford and I defer to anyone with more time spent at these vehicles.
Like Broncomania says the air filters, boxes, intake hosing and placement are also different. While researching those swirled spacer blocks for between the throttle body and the upper intake I became convinced by the application guides all the manufacturers had, that the throttle bodies were slightly different too, though I'm not sure I believe they are that different than 87s and up.
As for carbed 86s I believe, from what I've read, that all or most of the 351s were carbed that year, who knows maybe the factory used up the last few carbs on 302s too. I worked for Chrysler in the late Seventies, early Eighties and they were still sending us non catalytic equipped cars as late as 1980.
