Hello I have a 1982 ford f-150 with a 351 windsor. I am in the process of changing the intake manifold and the carburator. I had a motorcraft 2150 but due to mechanical failure it is now unservicible. So I bought the Summit kit with the dual plane intake and the four barrel carburator. All was good until today when I removed the old carburator and intake. I marked all the lines followed the instruction manual to the T. Now I noticed that there is a box with vacuum lines and electrical components on top of the valve covers. I was wondering if these were absolutely essential componets because my new carburator is not emissions compliant nor does the truck have to be. Also I understand this is a duraspark II system. The problem is some of the electrical lines going to the ignition coil are kind of cobled together. Can someone tell me where the esential wires come from that lead to this so I can replace them properly. Thanks for your help in advanced!

 

Wow, second time in less than 10 minutes... I just had to go back in my browser'
cache and copy-n-paste.

How do you know you have a 351W? Ford didn't begin installing those engines in
these trucks until MY1983:

http://web.archive.org/web/200702211...history04.html

If you really have a 351W, it didn't come that way from the factory.

 

Well I'm pretty sure it is according to multiple sources on the web including this web site it was availible in 1982. I have vin number G. Now vin number G is the engine code for the V8 351W CID 5.8 L 2bbl carb. This engine was availible from 1981 through 1985 in my trim package. Then there was a 4bbl version availible from 1984 until 1986. I will insert a hyperlink to a rebutable company proving this. Also this very website in the vin identification section you can find this very easily. So please sir next time you want to try to make someone look like a fool please make sure you have your facts straight so you don't upset people. I don't know who you are, I asked a simple question even if I was incorect you could have aproached my post in a diffrent manner. http://www.lmctruck.com/icatalog/fd/full.aspx?Page=11

 

According to the 1981 Ford Service specification manual, the 351W was only used in Econolines. However the service manual was printed in 11/80, so take that with a grain of salt.

Code G: 351M - 2V: E-150 With Leaded Fuel, and E-250/E-350
Code W: 351W- 2V: E-100 windsor only, and E-150 unleaded fuel.

First of all, I did NOT try to make YOU or ANYBODY ELSE look like a fool, I
merely asked a legitimate question since all the information I have says that
the 335-series 351M was the only 351cid engine offered in pickup trucks until
MY1983 at which time it was superseded by the 351W, and I didn't want to see
you back here asking questions because you're trying to fit the wrong parts to
the wrong engine. If you're seeing me trying to make you look like a fool, well,
I'm sorry you see it that way but it's something you are misinterpreting and
adding yourself, it was nothing I did.

I spent a good year researching my M-block engine before I did anything to it,
and it was during that research when I learned of when it was offered and
when it was superseded with the 351W. I provided a link(1) one of the most
comprehensive sources of information on the M-block engine to back up my
claim. Just like in school where you had to included a bibliography at the end
of your reports.

Many online VIN decoders are error-prone; for example, the VIN decoder on
this state claims my Engine Code "Z" is a natural gas-powered 300cid straight
six.

Similarly, aftermarket retailers of NOS parts (LMC, NPD, etc.) try their best
to keep things straight but they cannot be trusted 100%, either. The same goes
with auto parts stores - NAPA, Checker, etc. - though, in my experience, they'll
get it right most of the time. Cripe, even the Ford dealers get it wrong
sometimes, too (you should read NumberDummy's comments sometime).

Page 20-00-11 of my 1981 Ford Light Truck Shop (Engine) Manual shows
Engine Code "G" to be only:

351-2V 5.8L 8 Cyl

Since you are claiming the 351W was available in pickup trucks out of the
factory since 1981, please post some verifiable, reputable data showing that,
not merely "according to multiple sources on the Web." Just like in school,
cite your sources.

Sorry for sounding so rash. Can someone answer my question please? It's a 351w I don't know if it's original but I am assuming it is because it has ac [thats r12 and still works] and tons of wires that haven't been messed with that look original. Also the 351W manifold that I ordered fit perfect. I understand the M's have there thermastat in a diffrent place than the W's. Mine is in my manifold. Just like the one I pulled off.

 

Also reading your citation it says that it was dropped from production at the end of the 1982 model year. So this means that it was the only 351 used in these trucks at that time. It would seem to me that a company such as ford who invented the assembly line would want to gradually change there tooling, so they could ease into putting windsors in all F150's. By the sound of your article it seems ford was planning to make this change for a long time. So is it possible that they phased out the M's and and put more and more W's in these trucks throughout the 1982 year?
I don't know if you can consider Wikipedia as a good sorce. According to them on there F-series pickup page the Windsor was availible in 1981.
"In 1982, the 335-series "Cleveland" V8s were discontinued. The 351M was replaced by the 351 Windsor (an older design that now made its debut in light trucks), while the 400 vanished altogether (Ford's competitors had ceased selling engines in that size range a few years before). http://en.wikipedia.org/wiki/Ford_F-Series

 

Can you post the production date of the vehicle on the safety certification lable located on the B pillar right below the door striker bolt? as well as the DSO code?

Also can you tell me if the truck is catalyst or non-catalyist? that info will be on the emissions sticker on the left side radiator support.

This will help me help you further.

a picture of the device in question would also be of help.

In all honesty, you're probably right! You see, I have a 1981 F350, so I tend to
blow past the F150 stuff pretty quickly and not pay too much attention to it. I
just now went and read more closely some of that article I pointed you to, it
stated exactly what you had posited - that they phased out the M and replaced
it with the W in their various models over the course of a few years.

Probably the best people I know of out here who can say things authoritatively
are 81-F-150-Explorer & NumberDummy but it'd be up to them if they choose
to comment. Add to that, it was around 30 years ago, how much of it do they
remember....

Regardless, man, I wasn't tryin' to be a jerk or accuse you of being an idiot or
anything, I was just wanting to make sure you didn't go through the pain of
ordering the wrong parts for your engine, that's all.

Anyhow...

Oh, yeah, what was your question! I had to go back and read it.

Those doodads with vacuum lines & electrical connectors mounted on a valve
cover, yeah, do like 81-F-150-Explorer asks and post pictures. I learned all
about the emissions controls on my 1981 400 but that was 1-2 years ago, I've
forgotten most of it by now. There are various vapor separators & vacuum
amplifiers & valves & whatnot, it's kind of amazing what they could
accomplish without computers running the show.

But it sounds to me like you're gonna want to remove all your emissions stuff
at the same time here? That might be a bigger undertaking than you're
anticipating....

I am sorry for being so immature after all you probally have more experience than I do in this field. I'm mostly aviation so my apologies for being a jerk to you. I figured out that they are actually vacumm solonoids. Thats not an issue anymore now the problem is I have everything back together and it won't start ... No spark. Any suggestions would be appriciated. I just closed the hood and walked away to cool down until tomorrow when I have a clear mind. First thing I'm going to check is fuses. Any help is greatly appriciated!

 

Here's something else I say out here that sometimes gets me in trouble...

1. Is it plugged in?
2. Is it turned on?
3. Is there paper in it?

(Comes from people asking me computer-related questions ("My printer won't print")
without doing any diagnostic work on their own.) What I'm trying to say is, check all the
basics before delving into the more complicated stuff. I can think of two possibilities:

1) Something isn't plugged in/connected/wired correctly.
2) Your dizzy is off by 180deg.

Are you sure you're not getting any spark? Or, just not spark at the right time? Pull a
rubber boot off a spark plug, insert a screwdriver into it, hold the assembly near a ground
while somebody tries to start the engine; spark should jump from screwdriver to ground
as the rotor passes by the terminal.

Do you have a VOM (volt-ohm meter)?

-ct

P.S. Thanks for apologizing, that's pretty cool of you

 

No Spark?

Well, I need to know if its 49 state federal or California smog emissions. This info is also located on the emissions lable on the radiator support.

In 1982, 49 state federal had Duraspark-II, California had DS-III and EEC-III or DS-II depending on the GVWR.

 

According to the tag under the hood this is a EEC-III system. I checked the wires they seem to be hooked up correctly. I don't have a meter but I can borrow one not really sure what to check though. I am 99% sure the distributor is in correctly. I marked it before I pulled it out. But I will check one more time. Thank you for all your help!

 

With the EEC-III system, it could be a few things...

Coil
Ballast resistor
CP Sensor. (Crank Position Sensor)
Duraspark-III Ignition Module.
Magnetic Pickup in the distributor
Or the EEC-III Computer module.

Along with wires etc... etc....

If I were you, and you don't need the truck to pass smog, I would do a DS-II conversion to it, as the DS-III/EEC-III was quite frankly... Crap.

 

I hear ya I figured that. Considering doing somthing along those lines. I'll take one more crack at it. EEC-III once the pinacle of technology. That was a long time ago...
