Default Holley carb i.d. by number

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.

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.

Does the -4 number behind the 3310 make it a 750? 3310's use to be a 780 CFM. Just wondering . Lippy

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.
