Does somebody know a site, or a way to i.d. a Holley quad by the air horn number? CFM, or original application? Sure would appreciate it. Russ
Barnes and Noble, Books-a-Million and books stores carry the Holley books ... like the one above ... with all the numbers in it ...
i have a holley book and can look it up if you give the number. should be on the front driver's side of the choke, if you don't already know. it's usually a hyphenated 5 or 6 digit number; for example, the carb on my car is 7002-1.
Don't even have to look that one up....750 Holley vacuum secondary, 4160 style. And it should only have one accelerator pump, not two.
Yes, kinda!!! The original 3310 was a 780. When holley came out with the updated version 3310-1 it was now a 750cfm carb. same goes for all 3310- numbered carbs. Only the 3310 was a 780. These carbs are dual feed, not bouble pumpers. Edit, There were some 3310-1's that were still the 780 cfm rating. The easiest way to know for sure on the 3310-1's if it was rated at 780cfm it had the secondary metering block(one with changeable jets) whereas the 750 cfm only had a secondary metering plate(thin plate that you have to change to chage "jetting" as they do not have actual jets in the secondaries anymore. If you look at the carb, it should have a block between the bowl and the main body on the rear just like the front(except no mixture screws) that will be rated 780cfm. If the rear bowl looks like it is just attached to the main body without the block between the bowl and main body, this is the 750 rated cfm.
It's a 4160 style 600 cfm vacuum secondary, with Ford trans kickdown lever....supposedly "calibrated" for FoMoCo applications as well, although it's listed for replacement use on '70-'74 302, 360FE, & 390FE...fairly broad coverage. In reality it's a basic 600 VS, so you could use it on anything....there's no weird mixture tabs or so forth, like you sometimes find on OE Holleys. As a matter of fact you can still buy them new. I can look up the original jet size, sec. plate size, spring, power valve, pump squirter, etc. if you think it's been moogled with. Welcome to the H.A.M.B....!
Could you please look those things up? I would greatly appreciate it. I'm running it on a 67 cougar 289, is it a good carb to use or are there others that give better performance?
Shouldn't be a problem to use it, as long as it's tuned correctly. It depends on what else you have on the engine: intake manifold type, cam duration & overlap, & some other things. Another good choice for mild early Ford small blocks is the Autolite 4100, or the Holley 450 cfm VS. As a side note, I'd look at optimizing the distributor as well...if it's the original Ford points type, they aren't too bad, but typically they can use some attention to both the amount of centrifugal advance, and the rate. They also can suffer from bushing wear, which does weird stuff to the dwell & can cause some PITA tuning issues. People tend to overlook the distributor when they think about performance, and there can be quite a bit of performance to be gained for almost no $$- just some effort. The main jets are listed as the 122-632, which isn't serviced by Holley so far as I can tell; you could start with a 65 or 66 and be fairly close to that- although you may end up with somewhere around a 60, at a guess. The secondary metering plate is the 134-39, which has .073 main holes & .029 idle holes. The original power valve is the 125-208, which is a dual-stage 10.5/5/5 in. Hg piece. The accelerator pump nozzle is a .031. The secondary spring is the "black" spring. The Renew Kit is the 37-1536 (Holley official rebuild kit; it covers this & similar carbs) The Trick Kit is the 37-933 (contains most everything to rebuild the carb, plus some extra power valves, nozzles, pump cams, etc.) Both kits include the needle & seat assemblies, but not floats or the vacuum secondary diaphragm, which usually last quite a while anyway. Hope that helps a bit.
Maybe Homespun91 can help me out with with my holley carb ID. I'm looking to buy a rebuild, renew or trick kit for it and even though I've looked @ a lot of these sites, I'm still having problems with the ID. The top number on the horn reads: 3878261-EH. Under that is: LIST 3310. Under that is: 165. Visually it is: dual feed, vacuum secondary, has a secondary metering body, and a hot air choke.
It is a 4160 carb. The easy way to tell a 4160 is that the back float bowl bolts up to the carb body. A 4150 has a block between the back fuel bowl and the carb body. Just get a kit for a 3310 and you should be good to go. Larry T OK, let me try this one more time. If it's a R3310-1 it's a 4150 (with the block). If it's newer (R3310-2 or -3, etc.) it's a 4160 that the bowls bolts to the carb body.
Help I'm new here. I have two carbs I am trying to ID but with no luck maybe someone can help with a size here are the numbers R84014-1 /0423/12P-065813 The second one is D8PE-9510-ZA/ List 8418/1120/8418 Thats all the numbers I can find on them. Thanks
R84014-1: Holley 650cfm spreadbore, 4011 series; if you want the original jet numbers, etc. I can list them. It was an aftermarket carburetor, not OE. D8PE-9510-ZA: Ford OE '78-'80 2-barrel, 2150 series, originally on 302 engines. Don't know the size; likely around 350cfm at a guess. Measure the venturi diameter and the throttle bore diameter and I might be able to get a bit closer.
Thanks the R84014-1 is a duel feed I thought maybe it was bigger than 650(maybe a 750) the other is definitely a 4-V not a 2V I rechecked the numbers and they are right it has auto ford kick down and electric choke it has screws on both sides of the metering plate for lean and rich
Hmm. Well, the Holley listing is correct, anyway. The 4010 & 4011 series were designed as "easy to install" carburetors with little adjustment necessary...never really caught on, and are no longer made by Holley. Virtually all of them that were sold were either 600 or 650 cfm, although there were a couple of larger LIST numbers. I went back & checked that FoMoCo number, which is on a different document...same thing, listed as a two-barrel. Post some pictures of it if you can, or describe it in more detail. It's possible that it's a Motorcraft 4300A or 4350, in which case it should be a spreadbore.

While it probably is moot for the purposes of this thread; it should be noted that the "Holley by the numbers" books list MOSTLY automotive carburetors. There are a few agricultural (certainly not all) listings as well. Military, industrial, and most marine numbers are NOT listed in the books. Truck listings are also hit-or-miss. Again probably moot, but possibly worth mentioning: many of the list numbers in the late 1940's and early 1950's DIFFER from the identification number for the same carburetor. If you buy the book as I did, expecting a complete listing, you will be disappointed. Don't take this wrong, the book is certainly worth the price. It simply is not complete. I have at least 500 Holley numbers in my database that are not in the book. My expectations were simply too high. Jon.
