Engine/carb match up for a 351W?
 

Recently I bought a 1986 Bronco with a 351 Windsor in it. I was told that the engine in it was not the original one; I just found the block casting number which is D8E6-015E-D

I tried to decode it and I am thinking that it is a 1978 truck engine?

Anyhow, I am in need of a new carburetor, but I am unsure of what type I need. I have a motorcraft that is a 2 barrel, but I am unsure of which I need because there are so many out there.

Anyone well versed in this area??
:-huh

A 1978 truck engine would not be a 351W, but a 351M - and that is a completely different engine. So, if you have a W then it is from about 1982 or later, when is when they started coming in.

As for the carb, if you have a 351HO you'll need a Holley 4180 4bbl. But if it isn't the HO then you need an Motorcraft 2150.

This may be stupid of me to ask, but I am going to ask it!
How would I find out which engine it is? The previous owner told me it was a 351W, but who knows if that is really what it is. Thanks for clearing that up! I knew the 351w was a completely different engine, but I am not sure how to tell the difference. (I do not know anything about them, but I am learning!!!) Based on the block casting number I am thinking its a 78? If I am correct I do not know.

I looked at the Motorcraft 2150; it looks very similar to mine if not exact!!

This is the site I usually send people to for decoding help; the D8 on the Casting Number would be the year the component was *designed* and nothing more. Some parts are used unchanged for decades.

A 335 Series engine, which includes the 351C & M, and the 400, has 8 valve cover bolts and the fuel pump bolts are in a line vertically. A Windsor has 6 valve cover bolts and its fuel pump bolts are in a horizontal line.

Thanks so much for the information!! I went and looked at it and it is a windsor I am unsure of the year now that you mentioned that a 78 truck would not have a 351 W. :/

Thank you I looked at a similar site also; the more the better though! The truck is a bit of a Frankenstein and all of this information in the forums definitely helps!

So the Motorcraft 2150 goes on the Windsor? It appears similar to the current one? I was confused with what "HO" meant.

The 351HO was the high output small-block in the 84-86 timeframe. It had a Holley 4bbl carb, DS-II ignition, and no computer. There was also a standard 351W with the 2150 2bbl carb, computer-controlled ignition, and lots of emissions doo-dads. I think that is what you have, judging by the MAP sensor and other stuff in the pics.

Here is a pic! I think the carb is toasted :( One to many fires.. I just got the truck 3 weeks ago; its going to be a bit of a project, but the price was right. It runs, but needs a new carb (I think), versus a rebuild. Sorry for the huge pictures

That carb doesn't look too bad. And those are easy to rebuild.

Awesome!! Thank you, you are extremely helpful and informative!! I work at a shop as a auto body tech and I have asked a couple of the mechanics about the carb, and a lot of them know nothing about them and could not help me. I have a 1 barrel carter on my 85 Straight 6, and love it. Not a fast truck, but its been a great truck and good on gas.

So I couldn't be lucky and have the 84-86 timeframe :-X16
I will have to rebuild the Broncos carb then and see how it goes!

I may have to bug you again sometime in the future for more advice and problem solving!

Any time. You can PM me to get my attention, but starting a new thread will get me as well as many people who know a lot more than I do. Good luck.

Absolutely the easiest carb to rebuild, what part of the world are you in? The reason I ask is that a Motorcraft 2100 and 2150 are basically the same carb, however the 2150 is for high altitude applications (So don't just limit your search for the 2150). If you don't want to rebuild (It really is the easiest carb to rebuild and there are tons of YouTube step by step videos), I personally have rebuilt 3 of them. Rebuilt Carbs can be had on eBay from $150-300

Thank you for your message! I live in Florida; I tried calling around for a rebuild kit and the stores want the part number or the year of the truck because they tell me that there are a bunch of different rebuild kits.

I found this rebuild kit, but the gaskets look slightly different:

I checked out some of those videos and I am wanting to try it! I took some of it apart already and checking it out.

If I decided not to I found this, but it looks a little different than the one I have also..
