Heart of Dixie.....
Guys, Mopar nube here and just finishing up my first bb. Need a carb, my intake was cast in 1966 and is a square flange....so , my spread bore TQs won't work. I think an Edlebrock carb will bolt on with no spacer required.....but not sure if there is a better choice. Will a square bore Holley fit? I m thinking a 750cfm would be whats needed? thanks.....
 
I like Holleys. The street avenger series looks good and easy to adjust. Just my 2 cents

I'd go Edelbrock AVS2 model 1906. The AVS is the newer version of the Carter AVS carb Mopar used. I had a Street Avenger and fought that SOB for months. I've been doing carbs for 40+ years and that Holley made me go throttle body EFI. It's almost too tuneable. I always liked the AVS series carbs back in the day, and the improvements Edelbrock has done made it even better.

Just curious, what issues were you having? The one I had on a 340 ran great
 
You may want to consider a Street Demon carb with the phenolic bowl design to prevent fuel boiling/vapor lock with the Edelbrock carb.
 
if you have a good working Tq why not use an adapter and run it?
 
Dumb question, didn't the pre '70 cast intakes with Carter carbs have a different mounting flange pattern/spacing? Could be wrong, thought the latter Carter carbs & Holley's had the same bolt pattern. My DP4B had a dual pattern to utilize both.

You need to post the intake casting number before taking any advice
 
This is the stock intake, if I get it to upload, that I am planning to use. I found a brand new , in the box , Eldlebrock carb, that I purchased for another project years ago that has never been installed. The script says its a 750 cfm, manual choke and #9907. How does that compare to a 1407? I have piddled mostly with Holleys and Quadrajets but never any Eldlebrocks. I don t see much gain in the purchase of a new performance intake if using cast exhaust manifolds ...is that a fair assumption? In watching Nick of Nicks Garage dyno his 440 for his Kowallsky car , he made 400 hp thru a 70 stock intake and cast manifolds. But of course i m not sure of his cam and head choice. Think he was running a 780 double pumper also...

I hate running carb adapters and so not wanted to try a TQ but will purchase a new Holley or Eldlebrock if needed....thanks for your opinions......

A 1967 AFB 4327 is a 750 cfm auto HP less C.A.P.
4329 is a 750 “. “. “ with. “
4326 “ “ “ “ Man “ less. “
4328 “ “ “ “ Man. “ with C.A.P
Mine works fine.

Not to be picky, but the common "780" was a 3310-? vacuum secondary, dual feed. Not a "double pumper". Don't know what Nick had.
I think most (all?) Edelbrock versions were based on the Carter AFB/AVS.

How many dash numbers and variants of the 3310 are there,anyway?
The first 3310 was a 4150 style carb, rated at 780 cfm with vacuum secondaries, dual fuel inlets, (not a double pumper) and two metering blocks. From 3310-2 on, they were 4160 style, with a metering plate on the secondaries, and a 750 cfm rating.
And, to the op.... I would sure try the new edelbrock carb you already have in hand! My guess is it will work great. It's almost exactly what I would recommend .

Good. Its a "178" intake, used on 1967 through 1969 440 HPs. Just confirming.

Yes a Holley will fit.

Pick a any large - square bore carb (i.e. 1.75" primary and secondary throttle bores) of your liking in the 750 to 850 range. Holley, Edelbrock or Carter AFB/AVS.

The intake hurt power much more than the exhaust manifolds. So if its in the budget, get an aftermarket intake. How much it helps will depend on the cam you've choosen.
 
I do wonder why you would choose to keep the stock intake.
It is heavy. The only intake ever made that makes LESS power than the stock intake is the S P 2 P.
 
Thanks for your thoughts Guys. As for the "stock" 440 rebuild, this is my first dabbling at one and I wish to see the base line first. Plus, after many , many years of collecting parts, now is the time to use them up and begin transferring my cars and junk to new caretakers. It s time to start thinning the herd so my kids won t be so overloaded. Not planning a full resto on this one , just want to fry a lot of tires. The car is a 73 Charger that was a factory four speed and a PO had put in a Torqueflight and I wish to change it back. The clutch pedal assembly was left in minus the z bar and other linkage which I am in search of. I have an 833, bell housing , shifter and plan is to get that in at engine swap time. I got the 72 on the road two years ago and after the 73 is rolling , the 71 next , and then the 73 Challenger.....too much fun..

Boy not sure how many dash numbers for the 3310. I did think -2 was still a 4150, & after that came the 4160 style, could be wrong. Thought I had at least one -2 that was 4150. Maybe all the ones I had were -1's. The change in CFM rating came from the switch from the thin throttle blades to the thicker conventional thickness. I swapped the "780" throttle blades into my 4777 650 DP's on my tunnel ram to get to the "660". Can't beat a 3310-1 for versatility.

In response to bandit67 and this person's point if view, I offer the following comment.
If Bandit67, wants to maintain correct appearance and origionality, perhaps he could consider using an original Carter AFB carb such as noted above, as it works very well and is easy to tune. They are available thru eBay and other on line sources. The Edlebrock carbs (aka "Eddy's") are copies of the origional design but are adaptations, which sort of resemble the performance.
The Holley carb is a great product and as an alternative....but....you either love'm or hate'em....depending on one's understanding of how they work and ability.
The Holley 4150 R-3310-1 (and subsequently the R-3310-2) rated at 780 CFM is a great product. Subsequently the Holley 4160 R-3310-3, and later adaptations were rated at 750 CFM. Still a great design. However, the R-3310-1 carb has a hot air choke and may need to be converted to either an electrically choke coil or a manual choke, by using the Holley components to make the conversion. Personally, I've used the origional Holley 4150 R-3310-1 (with minor jetting changes) on both 383 and 440 engines with excellent drivability and performance with "reasonable" MPG.
The original Carter AVS carb is also an excellent choice, but not origional to the '67 440 engine. As noted previously, if origionality and appearance is the important consideration try to source a Carter AFB, if not buy what you like and can afford. Just my opinion of course.

I totally agree. For those that really "get" the Carter style, they sure work. My problem was every AVS, I tried to rebuild failed. I understood Holley's & had good luck with most(not all) with rebuilding. I remain a Holley guy. I had a new aftermarket Carter AFB on my tow vehicle 360. Worked fantastic for a long time. The 3310-1 choke took a little tweaking, then great. Over time a little a little adjustment needed.
