I have just recently aquired a 55' Ford F100 w/a 292 in it. Right now it has a old 2110 Holly/ford 2bbrl carb. on it, but I want to change it out for a 4bbrl carb. as I have 2 other manifolds. One that is for a 4bbrl carb. However I dont know what kind of carb. to get as it seems that all the new carb's are for newer engines with automatic chokes and electronic ignitions and the sort. The truck does have an electronic ignition kit on the old distributor. But still uses the manual choke. I am not very knowllageable in this field ..... quite frankly I dont even know if I'm making any sence. But I would like to put a 4bbrl carb on the 292 and need a little help with choosing the right carburator. Would appreciate any help on this matter.

Thanks,
Mason

 

You've got a few different choices. It depends somewhat on the 4 bbl. manifold you have. If you can get the casting number, it will help.

Assuming for the moment that your manifold has the newer bolt pattern (which is now the "standard" pattern; most people call it the "Holley" pattern because the vast majority of Holley 4bbls. use it), you have lots of choices. If you are interested in a Holley, I'd look at something that is a 600 cfm, vacuum secondary. A couple of numbers: the 1850 is a universal carb, calibrated for the average 300 to 350 CI engine. It has a manual choke setup for a cable. The 1850 S is the same carb in a "shiny" finish. The 80457 S is close to the same thing (based on the 1850), but has the Ford auto kickdown lever, an electric choke, & is jetted/calibrated slightly differently. Any of these will bolt on & work pretty well; if you are willing to work with it a little, you can change jets, pump nozzles, etc. to get it very close to perfect.

Another Holley carb you might look at is the Avenger series. The 80570 is 570 cfm, electric choke, & the 81570 is a 570 cfm manual choke. The Avengers are claimed to be a "bolt it on & go" carb. They are more expensive than the Holleys above, though, and hard to find used, since they are new to the market.

Other options would be the Edelbrock 500 & 600 cfm carbs, which are available in electric or manual choke. By the way, the electric chokes for both brands are a one-wire hookup- pretty simple. Just hook the wire to a "switched" power source which is only on when the key is on. The Edelbrocks are pretty easy to tune, simpler than the Holleys, if you are not familiar with carbs.

There are other carbs also; depends on what manifold you have, & how much money you want to spend. The older Autolite 4bbl works pretty well. I would avoid the old Holley "teapot" like a bad disease. I'm sure others can add to all this.

Hope it helps, Mike

 

I belive that the casting# is: ECZ-9425-A ? It's an original Ford 292 Manifold with Ford and the firing order stamped on it ...... and those are the only other numbers stamped on it.

 

thats the early manifold.it doesnt take modern carbs.you need ecz9425b.another thing to consider is youll have to change to a 57 up dist,to work with newer carb.

 

Yep, or, at least, if the existing distributor is hooked up correctly right now, you should. The older distributor is a double vacuum type & can be connected up to a newer system, with some work; but the '57 & up distributor, which is the "modern" (for points anyway) centrifugal/vacuum type, is easy to hook up & will work quite a bit better anyway. Or you can spend some more $$$ & get an aftermarket, like the Mallory.

All things considered, you might want to stick with the 2bbl. for a while & consider your options. Good luck!

 

I'd be thinking that the 292 needs to be checked. It wouldn't be standard in a 55.

So, verify the motor, because that 9425A manifold may or may not be a good match for the heads you have on the motor. If it is a match, then you can get an adapter to run a Holley or AFB Carter/Edelbrock.

But by all means, if you have the Load O Matic distributor, that's the first thing that needs to sleep with the fishes, before the carb or anything else.

If you don't work on carbs and don't want to start, why not get a 2v? An Autolite 2100 is about the most trouble free thing ever made, and they work well. Once you have the air cleaner on, you may not see much of the carb, anyway.

I've had good luck with the little 390 cfm Holley 8007 style 4v. But most any of the modern ones work well -- I'd choose based on what you like to work on.

 

All I can say is hmmmmm? I used to think that I was an ok backyard mechanic. But now I think I have a lot of learning to do. I am going to try and rebuild this little 2bbl carb. and see where it gets me, and I have been reading alot about how the "Y" block engines are woth keeping. But I see a complete engine swap in the near future, and might even go as far as an engine with fuel injection? But thatks for the help and advise fromm all of you guys. This site is the best !

 

My take on the Ford/Holley/Chandler Groves 2110 was that it didn't meter as well as a modern Holley 4v. But, it is very simple to work on and it's already there.

My wife has been bugging me about the "poor" mileage of my truck -- I can get 20 mpg with it. I've always assumed that I'd go with another Holley 390 cfm 4v, but then I've been thinking about maybe going to a Holley Pro-Jection setup. There are always one or two at swap meets. Also, I've been giving thought again to propane. I don't see the price of gas going down.

We've not built any refineries in this country for years, so it has to be shipped as refined products if we want more gas. Also, we haven't built any pipelines for moving stuff around, so any additional fuel must be shipped by tank cars on rails. It doesn't seem like anything regarding construction of new facilities in this country will change, so as long as the trend continues to be everyone buying large 12 mpg vehicles, the price of gas can only keep going up.

 

I wish I could get 20 mpg I do get a good 15 sometimes a little better but I figured that it is the shape (wind resentance) of our trucks that holds them back. But looking at modern trucks they don't do much better.
What are your thoughts on useing alcohol?

 

Wild Bunch (Timmy?), if you answer 57's question, how about a couple of mine while you are at it? What are the venturi sizes of the Holley 4150, 600 cfm, and the Holley 350 cfm two barrel? If you dont have that info stored in the memory banks is there somewhere I can find it? Checked the Holley site with no luck.

Re: carbs for Y-blocks;

Early three bolt Holley 94 carb on a compatible manifold, fits the smaller port heads like the ECZ-A ECZ-B ECZ-C.

ECZ- A 4 bbl intake, takes the Holley teapot and Carter WCFB carb and fits the heads above.

ECZ - B 4bb intake, fits the Holley 4160/4150 and Carter WAFB and Autolite/Motorcraft carb. Fits the big-valve heads like the ECZ-G and -113.

A new or rebuilt distributor, non-Load-o-Matic, can be had or well under $100. I got a rebuilt WCFB for $150.

 

NAPA's website was down this morning, but AutoZone lists the late distributors for $37.99 + a $20 core charge, for a '57 292 or 312 4bbl. Assuming that the correct one is actually in the box, that's a pretty good deal.

 

And, assuming the distributor "rebuild" was done properly, always an issue with the chain stores.

 

Mason,

I decided today to put an Edelbrock 500 cfm on my '58 292. I'll post the results in a week or so.

The install of the Edelbrock 4 bbl 500 cfm was slowed down a bit. Still waiting for the Blue Thunder manifold.
