8394 Views 19 Replies 7 Participants Last post by  David Ray
I have a Holley carb with the List # of 4223 and cant find it listed in any info on what this thing is.Its very different from others Ive seen,low rise choke horn with a funny looking bracket crossing right to left,center squirters,primary and secondary flaps open at the same time,also has vacume secondaries.It is obviously an older carb.
Thank you for any help.

This carb is , if my memory is still here, a cousin of the 4224 1:1 throttle plate , single feed, center squirter , 660 cfm carb used on many two four set ups. I ran a pair on my hemi cross ram and sbc tunnel ram cars. This carb is I believe a 600 cfm, these are short bowl 1850 style carbs.
Why would it have vac secondary if the base plate has mechanical 1:1 secondary?

Could be a conglomerate of various parts, aka, a basterd carb.

LIST 4224 is 1:1, no vac sec.

Or someone added the secondary? No real need as 1:1 and center squirter would dump all at once. I could not find this number in newer Holley manuals but 4224 is there.

Found a listing I am still looking into,
1969 427" ENG, HIGH PERF R-4223, AAS HOLLEY 4150 2065
The carb is a duel feed,it has the larger bowls like an old double pumper or 650,750,780,850 etc. It has 1 accel pump in the front.The throttle shaft end where you would put the cable or rod is very large compared to any other Ive seen,this is where the secondaries are also connected to the primaries.How do I post a pic on here? I doubt its a bastard carb because everything seems to go together with it like its supposed to.

What is throwing me is , I thought I understood "center squirter". I am not good at uploading pictures. Maybe one of the other guys will chime in. Suppose to be duck soup easy.
I hope I'm describing the center squirter thing right.Instead of the accel pump squirters being in the front on the primary end and being only 2,there are 4 squirters in the middle,2 for the primary and 2 for the secondary.

Notice side secondary throttle plate activation. Does yours look like this from the side? Asside from it being a dual inlet long bowl.
Yes,plate & accel pump lever look the same,but does not have bowls or the fuel tube.
Ive seen the 660 like that before but not the one I have.Maybe the one I have is a 750 or 850 version of that 660?

That is possible, I am also thinking it was a dual carb set up for something and or long bowls were added. I have done this with carbs sideways. But its the List # 4223 that I cant find anywhere in GM or Holley books. The information I found and pasted, came from a Corvette site. And I cant image any Vettes running around with this set up. Your carb looks like the progressive mechanical set up that I converted my 4224's with Holley 20-3 after market kit I had one left of and sold several years back , It could be tapered to a mechanical progressive center squirter carb. My old 1973 Holley book show this 4223 carb as a 1 3/4 bore base plate and being 850 cfm carb.. Page 76.
The 4223 is an 850 CFM "center squirter" carb listed in the Holley master catalog as a "High Perf 427" replacement carb (helpful, isn't it? haha)

It's basically a "big brother" the the 660 center squirter carb. It is mechanical secondary with a linkage very similar to the 660, but it has 2 metering blocks and center hung float bowls.

Hope that helps clear things up a little.

Eric, thats pretty much what I found but the fact that its a center squirter 1:1 ratio carb,( or am I looking at it wrong) is what confused me on what application it was put on. You just didnt have much room for partial throttle here, it was all 4 bbls all in or all out. I did find that it was list elsewhere for a 69 427 vette. 4224 660 cfm is a 1:1 ratio carb.
Great work guys ! :hurray: I knew I saved old junk for a reason.This is the perfect carb for my "Super Car" project. I'll hopefully be able to post some pics soon of my car.
Thank you for all of your help.

I forgot about something....whats the vacume pod for? Thought that was for the secondaries to let the fuel in?

Huh? Mechancial should have no vacumn pod. On what side of carb? Post a picture when possible.
Here's 2 pics if they come through.I took it apart a little while ago for the first time and discovered the power valves(yes,2 power valves) and jets are missing.Vacume pod is in the normal spot,right rear of center.

Dont know how to insert a pic,its says enter the URL? never dont that.I want you guys to see this thing.
You have an early HP carb. Very early. I would hang on to it.
Rob,
Do a reply to the post (not quick reply) and then scroll down to "manage attachments" Then you can upload the file from your computer. R4223 is shown as a 1969 427 HP carb.
