Cheap carb comparable to a #3310?

Basicly I can't find a holly #3310 for a decent price so are there any other carbs with comparable goodness that are easyer to find and just as cheap?

Get the 750 CFM Holley model 4010. It has annular boosters. They are on Ebay every once in a while. Usually for about $25 to $100.

You will get better mileage, 50+ more ft./lbs. of torque, and more power.

Humm I will keep an eye out but these seem to be as hard to come by as the #3310's.

when looking for 3310's you won't find another carb on the planet thats more plentiful except the quadrajet, but the carb to look for and have if you can find it is a 3310-1,it is a 780 with high performance down leg boosters.it was started at GM in 1965 on the 396 motor.the rest of the 3310's are 750's with straight leg boosters and a half pipes.still a good carb but not equall to the 3310-1.the rebuild kit for 3310-2,3310-3,3310-4, is about 25.00 but the 3310-1 is about 85.00.get the kit for -2,the -1 has stuff in it for many different carbs from the car manufacture's that have a very slight difference's on them so that when you're through with the rebuild you will have left over parts.instead just get the kit for -2,3 or 4 and you may have to buy one or two parts separately but they will not come close to 85.00.most knowledgeable carb people have high praise,s for the 3310-1.also it is the only 3310 carb that comes as a 4150 carb to begin with.i have all of these carbs mentioned and all but the 3310-1 have to have the trick conversion kit added to convert them from 4160's to 4150's.i am not saying the rest of the 3310's aren't any good, the -1 is just the better of all of them and i am infact using the 750 on my motor now.

Yea I had heard of the 3310-1 and its greatness. I just wish I could find any of them. No chance you would let one of your #3310's go (dosnt matter which)?

what do you have for a carb now?if you are able to put one together i think i almost have enough parts to make a complete carb.i think i would be missing the bowls.i 've got a -1 and two -2's apart overhauling them now but i'm not going to be doing it all right away.have other pressing matters first but like i said i think i will still have enough parts minus the bowls.the main body of this carb may need to be blasted though.when i was cleaning these carbs that body did not clean up like the others.rebuilders blast them then recoat them.don't know how exspensive it would be.i may have a 650.how big of hurry are you in?i just noticed you're in ohio too.

Yea I noticed you were in columbus after I posted the last message. I'm about 30 min from columbus.

Currently I have a 350 that I'm rebuilding and have no carb for it so no huge hurry. I could probably find a doner carb on ebay for the bowls. Only thing I don't know about is how I would assemble it. I'm generaly fine putting them together if I take them apart but never put one together from just parts. I'm not sure how much you would want for one but if your willing to part with that -1 and it wouldent be to much for my 350 then send me a pm and let me know what you would want for it.

I have a 3310-2 in a box in the basement. It was running rich when I removed it from a 383, may need to tweek it for your application. How about $100.00 and you pay shipping?

The 3310-1 sucks. I have a few of them trust me. The downlegs boosters kill all of your streetable power. Like I said, get the 4010 750 CFM Vacuum carb. It will run better than any other Holley, any Quadrajunk, and almost all of the BG carbs.

Read the new Car Craft magazine article about Annular boosters VS. downleg boosters. The downleg boosters lost 94 ft./lb of torque @ 1,800 RPMs compared to the annular. That is where you need the torque most for a street engine.

There are a million 3310-1 out there. Let someone else make the mistake of bolting one on their engine.

There are a lot more things you need to take into consideration than what you listed below.

With what you gave me I would go with a mechanical one, 650 CFMs or larger. How much larger depends on compression, gear, stall, cam, etc.

Run a Performer RPM Air Gap intake with the annular 750 Holley DP. You will have excellent bottom end torque and driveablity.

If you go with the Victor Jr. you will loose some of that bottom end. I don't know how much the annular carb will bring back. It should bring back some of the street manners.

I was also considering the air gap but here in ohio I don't think it would be a good pick because of the cold winters.

I will look into the 4010 as well.

EDIT:

No wonder I couldn't find any I was spelling holley wrong lol.
