Hello.
Is anybody out there running the Eelbrock dual quad set up on a 440?
I'd be interested to know how it performs and any tuning/running issues you may have.
Thank You

Almost every NSS car out there runs dual eddy's. One of the easiest to tune IMO. My car has run as quick as 9.59 and I know of many others including DVW on the board who has tickled the 8 sec zone.

Thank You
My car is exclusively a street car.71 Superbee with a 4 speed.
It's lumpy at tickover and the car is jerky when decelerating at lowish revs.

Most of us have heard for decades that multiple carbs are tough to tune. Running Nostalgia Super stock for years I know of no one who has had real trouble.

Most all of us have never had to change the set up once after set up anyway. It looks cool, and it works. Have fun!

I knew a guy who ran dual quad thermoquads using the adapter plates on an offy intake on a street 440 & it was an excellent setup. the carbs were identical numbers & were gone thru meticulously.

I ran dual Carter 500's on an underhood inline Edelbrock intake in the early 80's on my 383 Dart GTS and it probably was a bit much for the street, but it sure looked cool...

I Run a couple of Carter Racing Carbs. Love em, been running dual Carters since my first Hemi. Get some strip kits and go for it.

Our 1956 300 B hemi, solid lifter cam runs dual Carters from factory, rated at 355 hp(from 354 cubic inches,,,sorry 57 1957 FI Chevy), Idles at 650 rpm, 17 inches vacuum and will get 21 mpg on freeway with its torqueflite and 292 rear axle. Carbs have not been touched or tweaked in 30 years and runs perfectly.

I've been running two Carter 500cfm carbs on an Edelbrock intake on my 440 for a a long time. The carbs are tuned very closely to the way they came out of the box. There are no drivability issues. Certainly there's a legitimate argument that you can get better performance for a single carb. But you can't get the look.

You may need to clarify for us Yanks. Does "lumpy at tickover" mean runs rough after cold start up? "Jerky when decelerating at lowish revs", This one doesn't sound like a carb tuning problem. Maybe you need to shift to a lower gear? Push in the clutch?

Yes, some details will help.

First are you asking about just the Edelbrock carbs themselves or the CH28 2x4 intake and carbs as a package? The manifold, and there are several different ones, can have more to do with how 2 fours behave than the carbs themselves.

Stock cam? If not we need some cam specs to tell if "lumpy at tickover" has more to do with cam than carb.

Rear axle ratio? If it has a big cam, dual carbs and 2.76 rear gears it's not going to behave very well chugging around town in 3rd gear.

Check the tech archives on any BB Mopar configuration question. Odds are that over the last 20 years I've tested it and written up the results:

This.

Just not too sure the responses so far are in line with what the question is. I thought he was asking about the Edelbrock CH28 "set up"

From the original post all he is asking about is the carbs on a 440. No where does he state anything about the intake unless the post has been modified?

"Set up" implies to me a complete system. He asked about Edelbrock specifically so the kit Summit sells with the CH28 was the first thing that came to mind.

2 Edelbrock carbs on an OEM inline 413 intake are going to behave/tune differently than on a tunnel ram or MW type crossram.

Kevin

Maybe. I simply don't know what he is asking.

If you show me the word "carbs" then I'll show you "intake". And the sentence is written in the singular "the...set up" and not plural which would have been: "...Edelbrock dual quads..."

But then again, I sometime don't understand what I write.

Finally, without knowing both the intake, and the specific Edelbrock carbs he is inquiring about, I'm not sure how any response would be very meaningful.

Now guys, the OP specifically asked about "the Eelbrock dual quad setup" which is not what you are discussing. Eelbrock's are very rare and hard to find and only a few guys know anything about them. They have nothing in common with the Edelbrock carbs which people keep discussing.

My apologies 'lumpy at tickover' means when the engine is t running temp the ticover is not clean,it's up and down as if it's got a big cam.Idle speed is about 700

Jerky when decelerating,anything less than 2 grand

Please excuse my typo...............
