I think the reason Mopar didn't offer dual quads on a 440 it's that there was no market for it. They already had their flagship performance motor with the dual quads. Most guys who bought 440's were looking to save money over paying up for a Hemi. Not many would have paid up for the 2x4.
All this hogwash about the dual quad Hemi not being a good street motor will never die. I know from thousands of miles, they are the best street motor. Huge torque AND high rpm power. Very smooth, reliable and easy to drive and maintain in stock form.

Well Edelbrock sure made a nice setup whenever their CH-28 came out. Rather than copy early Chrysler and Offenhauser with a big open single plane plenum they made a true dual plane good to 6000RPM.
Keep old mopars alive.

Probably the same reason there was no large port version, and no solid lifter version.
Yeah I agree. They didn't do it because they didn't need to and/or they didn't want to. Mopar could've turned the wick way up in the horsepower wars but they didn't. Most likely because that wasn't the business they were in. It would've been very easy for them to put a 4.250 stroke crank in the 440 and make it a 505. They could've added the MW heads and a dual quad intake and buried the competition. Those parts all existed in the early 70's and hot rodders had built similiar combinations so they knew it was possible. They didn't need to do it and nobody really wanted to do it so it didn't happen. I suppose they might have regretted killing the big block since GM was able to keep their big block around in the truck division. Mopar probably could've done a truck version of the big block and kept it around a bit longer. GM is still selling big block crate engines but Mopar exited the business. I just got a new 632 from GM last week. GM is selling these 632 inch big block complete with EFI and coil near plug ignition. Makes 1000 hp on pump gas with a hyd roller cam so it will work great in a street car. Mopar could make something similar if they wanted but obviously they don't since they haven't.

IF they can make a Hemi head in standard form they can make one longer, make a longer block, longer crank (Chevy) Bilet cam, now there’s potential for really big cubes

The market was changing fast.

not sure if it's been mentioned or not but Chrysler did offer an over the counter dual quad set-up for rb engines. it was the 385hp 413 set-up with a cast iron single plane intake and two small afb's. chrysler never had the money to r&d and market a lot of combos for production the way gm and ford did. in the '60's most enthusiast were leaning toward single carb technology that was developing. this was basically born out of nascars ban on multi-carbs, and let's face it; most people can't work on one least wise two or three. i have far more problems with the single four on my stock '69 r/t than the dual quads on my '65 coronet. I think Chrysler just had a ridiculous number of engines as it was and needed another like a hole in the head. OFF THE TOP OF MY HEAD for 1970 Slant Six (170, 198, 225) The 170 was available on exports out to 1971 318 340 (different cams for manual and auto? can't recall) 340 6-pack 361 (Industrial out to 1974) 383 2 bbl 383 4bbl 383 HP 413 (Trucks and RV out to 1979) 440 4bbl 440 HP 440 6 pack 426 hemi I'm sure I missed a few variants but that is a lot of different engines to churn out and certify compared to today.

And I'm positive I missed a few. I think the 426 Hemi had two cams as well but just can't recall. Accountants hate part numbers, I bet they were positively bezerk back then based on my time working for Mopar in the 80's. Reduction in part numbers to increase the profit margins and save money was a constant mantra.

As small was Chrysler is to the other 2 they had a DQ intake for all 3 early Hemi's, the Poly, both low deck and tall deck B, Crossrams long,short and 1 pc and 426H intakes I would think they would have had it figured out as good as anyone and better than most.

You think that is bad how about ford? They had twice as many different engines, often 2 or 3 of the same size that were totally different engines with nothing interchangeable between them... talk about a cluster! GM wasn't much better with different engines for buick olds pontiac cadilac chevrolet... all getting their own engines and sharing engines sometimes. Chrysler had like 3.5 engine families in total thru the 60s and 70s

I love multi-carb anything. I have always wanted a 440 dual quad intake. I currently have a sixpack car, a tunnel ram with two 1050's Hemi car, a 383/400 sixpack, a 340 sixpack, two dual four street Hemi intakes and carbs, a cross ram max Wedge and a magnesium cross ram Hemi also.

Mopar could make something similar if they wanted but obviously they don't since they haven't. FCA has no interest in "heritage" engine platforms anymore. When they do have something like an intake for them, all they do is rebrand someone else's product and mark it up 30%.  I refuse to put anything with the Mopar Performance or Direct Connection logo on my car!
