2100 carb ?

[dalefan88]

my friend has three motorcraft carbs a 2100, 2150, and not sure of the third. how do i tell which one is the 2100 so i can buy it off him. the 2100 came off a 67 mustang but he doesnt remeber which one it is. the one i think it is has 1.08 stamped on the side. thanks for any help.

The 2100 and a 2150 look pretty much the same, except a 2150 has metering rods that move with the throttle. Also, a 2100 has a vertical choke pull-off on the drives side and the 2150 has a horizontal passenger side pull-off.

Here is a 2100 exploded diagram.

I've recently finished swapping a motorcraft carb for my Carter YF. If you're swapping from a single barrel to the M/C, you'll need a custom made adapter plate. If you're swapping in the M/C from a two barrel it's an adapter plate you can pick up from sumitt or jegs. Let me know, I'll dig you up the part number.

As for the hole, you'll just need to fill it with some silicon so that you're not sucking air in that isn't going through the air filter. Speaking of filters, do you have power brakes, if you do, you're pretty much Limited to a 7" round. If you wants some pics, let me know, I'll put some of those up to.

One more thing, check the jet size in that carb. From what I've read and tinkered with 46-48's are the size you want.

wouldnt it be better to start off with a 2 barrel intake? I think keeping the 1 barrel intake woulb be like sucking through a straw forgive me im just rambling on

Kind of. But it's a big straw. It's not like the single barrel intake is equal to one of the two holes of the two barrel intake . If you go by circumfrance, the single intake hole is probably almost equal to the size of the two holes for a two barrel intake. It's all about the amount of CFM's that the engine needs. The same way that a four barrel intake isn't equal to four times the size of the single barrel intake. Am I making any sense, or am I just rambling

Hopefully these pictures explain it better than I can.

i have manuel brakes and replacing a 2 barrel bbd.

 

[gert]

well that should make a n easier swap

 

[dalefan88]

is there anything else special i need to know doing this swap. like troddel hook up or vaccuum lines or anything?

 

[gert]

ya get with elwood but I dont think your throttle linkage is gonna work

 

[elwood blues]

gert's right. The carter BBD and YF models are down pull carbs. The Motorcraft is a rear pull. Here are a couple of pics of the linkage I fabbed. With a dremel and a cut-off wheel I cut the bottom of the original linkage plate off (the part with the square hole in it to hold the throttle cable still) and I had a friend tack weld these pieces of angle iron I had laying around. I bolted the homemade bracket to a couple of holes already in the rear of the exhaust manifold. Sorry about the second picture, it's pretty blurry.

The vacuum lines can be a little tricky. The schematic was helpful.

These two write-ups are also very useful:

Here's a good place to get motorcraft jets:

And the adapter plate, from what I have been reading, the ones sold from summit and jegs doesn't exactly match up correctly, I got mine from this guy; Michael Ehrmann <michael.ehrmann@hotmail.com>, $35 including shipping, he also sells complete motorcraft carb swap kits, but don't waste your money on the linkage adapter kit, it isn't worth the money, IMHO.

Wow.. I wish I would have found that one before I rebuilt my 2100. That is the best I've seen as well.
