Cashcrazy Anyone buy a MC2100/2150 one from the eBay guy? The ad says it comes with instructions to adapt the factory breather. Just curious how it looks.
06-29-2013 05:57 PM
roadyrob there will be a part number on the choke horn, google it and you will get the size. as its on a 258 my WAG would be between 390 and 500 cfm. your loosing alot of power by running it with an adapter, better off finding a 4 bbl manifold.

impulse250 Lol. Somewhat of a joke lol. Good job!!! Actually I'm curious what model by Holley. I'm not to sure how to distinguish that....
06-29-2013 04:56 PM
89Saharagreen Is this a joke it says Holley on the front?
06-29-2013 04:36 PM

I have the 70's Carter without a stepper motor. It's alright... It's starting to fade on me though (not sure when or if it's ever been rebuilt)- either need a rebuild or upgrade... My YJ didn't like the timing set at 12BTDC though - it was too much. Had to back her back down to about 8-9... She seems to like that more.

Beachcruiser My carb cost me 90 bucks to install (total, with self rebuild, adapter, etc).

The most common application for the 1.08 ventur1 2100/2150 that works best on the 4.2 Jeep is from a Ford 302 (68-81, used in everything from Mustangs to F trucks)

Not only can you find them on Ebay for as little as 45 bucks, but keep an eye out on Clist, local 4X4 forums & mustang sites.

Mewing8 Jeep went to EFI 4.0 in '91. B4 that it was a 4.2 and had a carb. Get Howell EFI conversion kit, cheap compared to other brands, at wound $1,200. A good carb will cost you about $300.
05-21-2013 01:21 AM
Keymo LUCKY!!! Haha! I need one of those babies!!
I think I can see the tag in the picture... But there will be a tag or stamp somewhere on it with the model number...
05-18-2013 12:37 PM
Billmummey A friend of mine gave me his from his bronco and i know it's a MC carb but don't know what one it is... I have a weber on my 4.2 now an hate it!! There are 2 adapter plates under the weber now so I'm hoping that is also the one that fits the MC
05-17-2013 07:07 PM
impulse250 Really? From the pix on the Internet of the 2150 this carb on it now looks nothing like em lol
05-17-2013 06:36 PM
Nubby55 if it's got a holley on it, that what the Mc 2100/50 is a copy of, it's a 350cfm or a 500cfm, ether one is a fine carb for the 4.2. The 2150 is about 350cfm, honed and polished you can get about 400cfm out of one.
05-17-2013 06:12 PM
impulse250 Hell yes. Thank u! I actually wonder if mine already has it on it bc the previous owner out a bigger Holley carb on it
05-17-2013 03:01 PM
Keymo And that conversion plate is specifically called:
"2Barrel Roshester to 2Barrel Holley Adapter"
The part number for Advance Auto is SUPPOSEDLY "P/N 1937" Though I haven't CONFIRMED this....

Yeah... Theyre on most 70s to early 80s fords (I THINK)... I have a list of the specific models I'll try to find...

And yes. You'll need the gaskets and a "large 2barrel to small 2barrel conversion plate" (theres also a specific carb conversion name but i forget right now - ill look it up in a minute) i know you can get them from advance auto and other various places...

You can off eBay.... But they're expensive - like 150-280 for the "buy it now" ones... Better off finding one at a junkyard and cleaning/rebuilding yourself.. You'll save like 100 or more... That's what I'm holding out for! Haha!

05-17-2013 10:32 AM
Keymo Yeah... The MC 2150 is definitely an AMAZING carb. Have one on my J-truck and there's this mini-hill climb area outside of town that people do - had her at some INSANE angles (uphill) and she's never cut out on me. I'm trying to find one (not one of the expensive ebay ones - I'm all about rebuilding it) for my YJ.
05-17-2013 09:16 AM
impulse250 Lol! It's all good! Ya unfortunately my 1990 is carb. I had a 91 a few years ago n never really had issues on hills with the carb, Only if I was on a really really steep hill it would cut out some
05-17-2013 08:56 AM
Keymo Ah! Sorry! I wasn't aware of your model year... My bad!
05-17-2013 08:53 AM
impulse250 I think 92 or 93 was the year they went Injected on the 4.0. Not sure though
05-17-2013 01:59 AM
Keymo If the OP has a 4.0L should that not be injected already?
05-17-2013 12:21 AM
