I was wondering what the history and changes of the f -series (bullnose)
1980-1986?

body changes/ engines/ technology/suspension-frame ect.

 

Here's a couple of links from a quick search.
Previously I've found a site with more tech detail somewhere, but this is a start.

Ford F-Series seventh generation - Wikipedia, the free encyclopedia
The History Of The Ford F-Series In The 20th Century

 

One thing that isn't mentioned in the Wikipedia entry is that the frames, at least for the F100 & F150's differ between 81 and 82. In 80 & 81 the frames had holes in the vertical portion to lighten them, but as of 82 they went back to being solid. Some say that was due to a public outcry over what is called the "swiss cheese frame", but there is seemingly no evidence that the lightened frame was inadequate.

 

the main reason/s I was asking is #1

at my local pick n pull the have several trucks / vans that are 1980-85
most with 351,302, 3.8 ,and only 3 vehicles with the 300 ( all 1985 "sigh" yes that's what mine truck is but I wanted older for engine parts sake and emissions minimum ) and yes the only 3.8 V6!!! I have seen in a bullnose (1982 I think)weird

the body panels are a bit different 1980-82 I think too

what is the types of technology in these trucks also engine, emissions, ect

the reason is parts I want my 1985 f150 to 1982/3 or older type technology

already have dps ii and a lean ( yfa) carb but a Motorcraft 2v is in the works

thanks for the replys ! p.s. I love this era of ford but their vacuum and pollution controls are a pain in the ...

 

I don't understand what the actual question is. But, on body differences Wikipedia says:But, if you have more questions please be more specific.

 

oh well that explains the body issues!

sorry but I was asking what types of emissions equipment are on the different years what changed, why this vacuum hose was routed here ect. what id they use and why?

1979/80-1986

 

That's a huge question. And someone better educated on these trucks than I should answer it. But, here's a bit of info on some of the systems used:

• AIR: Stands for Air Injection Reaction, IIRC. A pump was used that added air to the exhaust gas to aid the burning of un-burned hydrocarbons. There was a diverter valve that determined where the air was injected - usually into the exhaust at the valve in the head or just upstream from the cat.
• DS-III: This ignition system had a distributor with no vacuum advance, and timing was handled by the computer.
• EEC: The computer. Some versions ran the ignition system, carb or EFI, EGR, diverter valve for AIR, and various other things.
• Feed-back Carbs: Some carbs had a solenoid that was controlled by the computer and that varied the pressure within the carb to change the air/fuel ratio.
• Catalytic Convertors: Typically trucks under a certain GVWR, like 8600#, had cats while those above didn't.
• EGR: Exhaust gas re-circulation added inert gas into the air/fuel mix under certain situations to reduce to temp of the combustion process, thereby reducing the emissions.

Maybe someone else can fill in the models and dates.

 

Air pumps and EGR were used since the 70's, DS-III, feedback carbs, cats came in the 80's. Different weight classes had different emissions.

What specifically are you looking to do? There are articles floating around here on how to do a DS-2 swap with a non-feedback carb. EGR is easy enough to make functional and AIR easy enough to remove. You may want to look at 70's era trucks for appropriate brackets if you want it to look factory. The cat... They don't hurt anything so run an aftermarket cat so we can breath easier...

However, it's not going to pass a visual emissions test if you have one.

 

The '78,and '79 trucks had a bullnose look to them too

 

F100/350 related.

Smog (air) pump (FoMoCo: T/E = Thermactor Emission) introduced in 1966 F100 240/352, mandatory in sold new in CA

EGR valves introduced nationwide in 1973. Catalytic converters introduced in 1975 F100's.

Evaporative Emission System (Evap/Em) introduced in 1970 F100, mandatory in sold new in CA

You wanna know what's correct and what ain't? 1980/89 Ford Light Truck Parts Catalog available on a CD from hipoparts.com

Wiki Wiki is a poor choice for information, regardless of what it's related to.
1978/79 F100/350's have a 'fish mouth' grille, rectangular or round headlamps. Otherwise look the same as 1973/77 F100/350's.

All the sheet metal is exactly the same excepting the Styleside left quarter panels. 1973/76 Stylesides have exposed fuel caps, 1977/79's have fuel doors.

1977/81 Couriers have a stubby front end, slanted headlamp doors. When the 1980 F100/350's came out, their front end mimicked the Couriers.

People either loved or hated them. When the 1987's were introduced, some people rejoiced, including yours truly.

 

Someone flat-out made that BS entry up. All sheet metal from '80-86 is exactly the same with the limited exceptions of a few things... the radiator supports being the only one I can think of, but that was based on engine option and varied truck to truck (small block/six, big block, Diesel).

 

I should be able to bust that myth in a few days. I have 82 doors in the attic and 85 doors that need to go up there. So when I take them up I can stand them up side-by-side and compare in a pic. And/or I can do the same with fenders.

 

I have an '80 and I had an '86, seen countless trucks in person be it driving around or in junkyards. Fenders are the same, doors are the same up until the early/mid 90's when they put a small crease in the bottom of the door (does not cause fitment issues and can be easily filled). Beds are all the same until '87 with the exception of the tailgate strap mounting location if I'm not mistaken. '80-86 bodied trucks all share the same directly interchangeable sheet metal. Who ever posted that info on the Wiki site was probably looking at pictures of the tu-tone trucks while wasted out of their mind... This tends to distort and add/remove body lines.

 

They may look the same, but looks can be deceiving.

 

So you think that the 1987 - 1991 models look better than the 1980 - 1986 models?
