I have a 3310-1 on my '67 with the 327/350. It came on the car when I bought it in 1975 and has run well. I can only assume the owner had problems with the original carb and went with this. What is the deal on rebuild kits. In the past I have rebuilt this carb with a 37-1084 kit and a 37-332 kit. These kits are pre-internet when you went to a parts store and asked for a rebuild kit. Maybe they were the only Holley 4bbl kit and the guy knew less than I did, who knows. I called Holley the other day and he says I need either a 37-1539 or a 37-933 kit. Both these kits are over $100 while the price on one of my other bought kits (granted, I bought them a while ago) was $24.95. In my research one person on another forum said the 37-1084 is the kit I need and was on the 396/425 engine. Anyone have experience with this carb and can give me some advise? thanks.

The kits have been combined to cover more models over the years, increasing the number of unneeded parts in the kit and the price. The Holley web site shows that the current Renew Kit is 37-1539. The 37-933 is a Trick Kit which you dont need. You dont mention why you are trying to rebuild the carburetor. An economical way to refresh the float bowl related components is to buy everything separately. Two each of power valves, needle and seat, float bowl gaskets, metering block gaskets. One each of accelerator pump, secondary diaphragm.

Thanks for the info Mel, it stumbles when you get on it, I figure accelerator pump diaphragms. Plus it hasn't been apart in probably 20 years and I wanted to clean it up both inside and out. I rough priced out parts in a Summit catalog:
2 power valves $20
2 needle and seats $28
2 accelerator pump diaphrams $7
intake gasket $8
metering and fuel bowl gasket set $12
Total $75

At that point, I'm seriously thinking of just buying a new 3310 for $330 and just having to unbolt and bolt. Unless the new 3310's are inferior to my 3310-1.

the "new" 3310 carburetors are 4160 series, no metering block in back just a plate and are rated at 750 cfm not 780 cfm like the 3310. You are better off looking at the Street Avenger 770. You mention 2 pump diaphragms, I assume a typo because you should have only one.

If you're going to go new, you might as well buy the series of Holley that originally came with your car...a 3810. They're not cheap, but I can assure you they will perform better than a 50 year old rebuilt carburetor

Good catch, my error, I thought it had 2 AP's.

Last year i replaced a 3310 on my 1970 396 350hp chevelle was having problems with carb it was 10 years old and probably needed rebuilt.

I went with a street avenger 770 they come with electric choke and quick change vacuum secondary spring.

Installed and just set idle adjustment screws and played with choke a little could not be happier jets seem to be close enough for my motor.

I would think that you mite want to go with one size smaller if you decide to use a street avenger the 770 is pretty big for stock l79 .

I always thought that carb was too small for the 327/350 especially if you have 4 11's out back like I do. Is the same jetting on both the 300hp and 350 hp engines? I would think not. Be nice to be able to have the original fuel lines on the car though. Thanks.

TWINRAY

Thanks, I see that carb coming up in a lot of people's choices.

Many people over carb their car thinking more is better...not the case. You can "drown" your combustion chambers with too much fuel. The Holley List 3810 that originally came on the L79 is more than adequate for normal driving.

I have a 1966 with a Holly, I had several people tell me they could rebuild my carb, after several failed attempts by those same people I bit the bullet and sent it to Holly. It was like new when I got it back, I put it on the car and never looked back.

Good advice. I always felt overcarbing was a mistake. Too much raw fuel in the cylinder washes off lubrication leading to premature cylinder and ring wear.

I assume that carb was a list 3367. They sell new Holley reproductions for$700 Did not know Holley still did rebuilds. Thanks for the info. I will keep that in mind.

I've been using Holley carbs since the mid 1960's and there is nothing better. They are basic and easy to understand if you take a moment to "try" to learn how they work. The 3310 has been the workhorse for many years. ANYONE can rebuild one with just a little effort. If you have the big bucks buy the special kits for them but you will pay an extra price. Bowel, metering block, base plate gaskets are the main items. Get the hi-po float valves and use a little trick I learned many years ago. Grab the tip of the needle that sticks out with a pair of needle nose pliers and press in just slightly and twist it 90 degrees. Takes the shine off the Viton seat and makes it work. Use Holley's chart to determine the size carb you need and READ all their instructions. My 496 BBC is working just fine with a Holley 850 DP

I am no holley carb expert, i have been told that a street avenger is a 3310 with just more bells and whistles, i was happy when i changed my 3310 to a street avenger with electric choke and quick change vacuum secondary springs on my 1970 chevelle 396 350 hp.

Had my 3367 rebuilt on my 66 l79 and it works great

I dont think you can go wrong with either carb .

All o the major ignition companies have carburation parts and kits...Brands that are such available are, Standard ignition, Borg Warner. and Filco.....Not available through chain stores however....Your large independent stores carrying one of those brands could order the necessary kits and parts....They also have interchanges to cross carb part numbers........I agree, the 3310`s are a bolt on fix.......and I don't think they are available as new any more....
