Hey guys:

When I bought my truck, it had an old Holley 4 bbl mounted on an adapter. Used it for a while and then, over weekend, front bowl got stuck, leaked gas all over and caught fire! Quickly put it out and no damage other than a couple hoses that needed replacing anyway. Don't want to mess with a rebuild of that carb. Would rather go back to 2 bbl. and buy a remanu.

Looking at pricing, etc. online, I see that OE was the Motorcraft 2100 (C895A). Looking at parts stores, ebay, etc, I see rebuilt C895A's (Auto-lite) going for $200-$300.

But, also, there are 2100's (A800) which go on Ford small blocks and some Jeep big blocks, including the 360! They are selling for +/- $100. They seem to be very similar, maybe slightly smaller venturi, etc.

My question, is there any reason I couldn't use the A800 2100 as it looks very similar to the C895A 2100? I know either will bolt right on my manifold without a plate, etc. I'm sure hoses may be in different spots and I believe both have automatic chokes. Just trying to save a few bucks.

Thoughts?

The ebay clones from the ones I have purchased have a 1.21 venturi which is fine for a 360. I personally haven't had issues with any of them.

 

Thanks for the quick reply. So, you're saying the A800 version of the 2100 can work, correct? Also, it looks like OE on my 360 originally had an electric choke. There is a couple wires from the firewall coming down that look to me to plug into a choke assembly. They weren't being used with the Holley.

So, does it matter whether I get one with an electric choke or do I need to be looking for something else...as far as the type of choke I need to have? I believe the ebay clones look to have an automatic choke...is that correct?

 

Your truck does not care if it has a manual or electric choke as long as things are properly installed and well adjusted. Plenty of old threads on this site to help you accomplish that task. I have one of each on my Dents and they both work fine.

 

2100 series 2V: 1963/72 is Auto-Lite; 1973/74 is Motorcraft.

 

My bad Bill. This is what I get for posting with a migraine! Meant Motorcraft and Auto-lite.

Still, just trying to confirm that either one can work whether it's the C895A or the less expensive A800...

 

My personal experience, in dealing with "remanufactured", I bought one from local parts store, just due to lack of time, and impending surgery. Spent around $220 on it, and within 6 months I was having major problems. Tore it apart to find the cheap Venturi Boosters they used during "remanufacturing" had come apart. Original, rebuild able core MC2100s are easily available for cheap (less than $50), a rebuild kit is $20-25. They are very simple to rebuild, even soaking the parts I can have them tore down and assembled within 1 - 1.5hr.

 

I'm still struggling with which way to go with the ebay clones. There seem to be 2 versions of the 2100. An A800 for under $100, and a C895 that goes for $200+. They BOTH look identical. However, it says the A800 version of the 2100 fits small block ford and the Jeep 360 big block, which I believe is almost the same engine as the Ford 360, which is what I have. When I plug in my truck specs it says the A800 version is not compatible and that I need the more expensive C895 version of the 2100

But, I believe either of these carburetors will work. they are both 2100's! I'm thinking I'd just go with the cheaper A800 version of the 2100. But, I'm still trying to understand the difference between these 2 versions of the 2100. Does anyone have any insight?

 

You are putting too much thought into a simple purchase. Unless you need to be emissions compliant go with the A800.

 

There! Thank you. I was just waiting to find out what (if anything) the differences were between the two versions of the 2100. I suspected emissions, but could not confirm. Very little info online to differentiate these two versions of the same carb.

 

Should note that though they are both "2100s" There are many variations, Emissions aside, there are multiple venture sizes which effect the CFM of each carb. The A800 looks like a 1.14 venture size, which will work with a stock 360, and I believe that came factory on some. My personal preference would be more inline with a 1.21 venture, which in my experience was more common on the FE motors.
The C895 seems to be a true Motorcraft unit that has been remanufactured vs the A800 being a replica/replacement. As long as the A800 has a semi-decent warranty, give it a shot.

 

Thank you Skyhawc. I think your assessment is spot on. I'll probably roll with the A800 and see how she does. Engine is original and fairly stock, other than headers and new head gaskets.

 

I'd get a 500 cfm Holley 2300... two barrels.
