Can someone please explain a few things
What is the diff between a 3310 & 3310-1?
How does it compare to a street avenger?
Finally are Edelbrocks worth considering?
I really don't like messing with carbs-want to get the best setup and just drive! ;)

I don't believe there is much difference between the 3310 and the Street Avenger, other than the zinc coating on the Avenger. The 3310 and 3310-01 are the same. For a street car that you just want to get in and drive, it's hard to beat the Edelbrock or a properly-tuned Quadrajet. Holleys can be more tempermental, but once they are set up, they can be reliable, too. I've had experience with all three, and you can't beat the Holley for all around power, gas mileage with the Quad, and a combination of the two with the Edelbrock (Carter AFB). The Edelbrock was down on power to both the Holley and Quadrajet, in my experience, but very easy to tune and get to keep a tune.

68- are you sure the3310/3310-1 are the same ? In another post it was mentioned that they switched and to be sure to get the "-1". Thanks for the help! My car is a clone ss also, 68's are sweet! :D

Can't help on the 3310/3310-1 issue, Holley doesn't list a 3310 on the numerical listings section of the web site, just the -1 through -6.

The -1 would be pretty elderly. Therefore, perhaps pretty worn-out.

The same carb was sold as the 0-9188, it was a vaccum secondary 4150, it had the correct hot air choke and the downleg boosters, whereas all the later 3310's were 4160's and had crappy straight boosters.

I really don't like messing with carbs-want to get the best setup and just drive! I'd go with the Edelbrock. IMO, this is a far better carb for someone that wants to just drive.

For a mild street car, there really is no performance difference between the various carbs, at least not noticible (for serious racing, Holley's better). I have actually had several cars run slightly better at the drag strip after switching to Edelbrocks (street cars running 12.90s to mid-14s).

If you don't want much tuning, etc, then I'd look for a new carb instead of used...

On the 3310, one has a metering block while the newer has a metering plate. You must change metering plate for jet changes, where as on the block you change the jets only.

Seems like to each his own. L-78 what kind of set up did you run the edelbrocks on.
Schurkey/Hi-po ss thanks - how do I know if it has a block or a plate?

3310 is a 4150 780 cfm, 3310-1 is a 4160 750 cfm, the 3310-3 is the oone with the plastic parts, etc. Every time it gets revised, the number goes up. The 3310-1 is an old carb, they are probably up to 9 by now. You can tell the block from the plate just by looking at the front side. The block on the front has the idle mixture screws in it. If the back has a block it'll be like a mirror image of the front, if it has a plate, the bowl will be closer to the body.

Thanks ZZ69- so is the old 4150 format better?

If you like to tune it is, the rear block has replaceable jets, whereas the plate is set at the factory and isn't ajustable (without drilling). BTW, Holley sells a metering block kit to convert the 4160 to 4150.

Thanks Z - any thoughts on the avenger or edelbrock. I am not good with carbs . :eek:

According to Holley http://www.holley.com/HiOctn/ProdLine/CarbList.pdf a 3310-1 is a 4150 780 cfm and the 3310-2 through -6 is a 4160 750 cfm.

The avenger series is a 4150 carb. The edelbrock has fewer circuits, both are good carbs...

You'll probably get a hundred different responses saying X is better than Y, but the best carb is the one you buy, learn about, and tune to your combo. Get a book on the carb you go with and it'll really help. Carbs aren't as complicated as you may think. I prefer Holley carbs, but I really don't like to recommend one over the other, I'm just more comfortable with them.

Fair enough! I guess its time to do some reading! :D thans z

I agree, here's some good basic's on Holleys that give you a brief look at the different circuits within the 4150-4160 carbs. There's a link to many books also... http://www.camaros.net/techref/series_2.html

To clear one point up, the plate on the newer 3310 must be replaced with a different size jetting which is available. Holley does not recommend modifying the plate.

Dennis = I took a quick look at the camaro/holley info . Looks like a great place to start! graemlins/thumbsup.gif
