Quick fuel "Q-850". Those have the 1.750 throttle bore with a 1.400 Venturi.

850 dp minimum imo............. the right foot determines how far the throttle plates are opened, even at WOT Every Mopar B or RB motor I've palyed with loved more air and fuel, even sixpaks or tunnel rams

I agree with ^^ these guys as well and 850 will allow you to make a few other mods to the engine retaining the carb.

One thing no one has asked.. is this a trans brake or foot brake car.. a trans brake can use a big carb but a foot brake car you have to have good throttle response to get the rpm... I was running a 1050 on a 405ci but with a trans brake

My 440 has run best using a 750 Holley DP carb.The 850 didn't work as well.

The smallest carb I'd run on a healthy 440 would be an 830.

I took a 950 off my little 318 and put on a 750, slowed the car down a tenth. Picked it right back up putting 950 back on. So with a bigger motor I suspect the results would favor a bigger carb

i just picked up an 830Hp 4150 for cheap, then started doing some reading, it has the 1.56" venturi.
i would maybe look for a holley 950DP, as the venturi is smaller than the 830 and 850 holley carbs, might work better. maybe consider picking up a clean used one (any of the above ^) and send it to Thumprdart to get adjusted...

Ran an 830 DP years ago on a mild stock bore 440 with a 528 flat tappet purple cam. 10.1 compression and it ran great on the street and track at 3600 + lbs. I'd think that you would want to run an Edelbrock carb on your setup since they weigh a lot less than a Holley. (although the newest all aluminum Holley carbs are getting to be fairly lightweight)

I surely wouldn't recommend a carb based on weight and NOTHING including efi out performs a Holley carb in single and dual applications.........
