There are no part numbers stamped into the base or lid

Here’s one https://www.ebay.com/itm/325359405437

If you’re running the factory intake I’m not sure that carb will work. Isn’t the street demon designed to be used on an intake with an open plenum? It looks as if the secondary butterflies would hit the plenum divider on a factory intake and never work. So yea we’re gonna need some pics of your...

I was thinking it was a 440 car for some reason.

Well 3/8” is pretty much the difference in height of the base between a 383 and 440. So is this the original air cleaner base to the car?

@Woodruff Carbs he does great restoration carb work

Not that I’m promoting drilling the primary butterflies but they can be soldered up if needed.

If the goal is to delay the metering rods pink is the wrong direction maybe try the yellow first and still rich try the blue. If still rich you can rule out the metering rods opening too soon and move on to rod and jet changes.

do you still have the pink springs in? I think you should go the other direction with the springs the blue spring is the lightest and the silver the heaviest so you moved to a heavier spring and really need to try lighter ones so I would try the yellow then the blue.

Ok so at what point in the rpm do they begin to come up?

Did you check to make sure the metering rod pistons were staying down at idle?

If your springs are too light you will have a hesitation/bog when you step on the throttle if they are too strong they will dance up and down or open too early and cause a rich condition. They should stay down at all times during idle and cruise you only want the rods on the step up under hard...

They should stay pulled down until the vacuum decreases enough that the springs overcome the vacuum. you can loosen the doors over them and rotate them over enough to see them and the cover still holds them in. that way you can see if they are up or down or dancing up and down. They should be...

I have two 650 AVS 2 carbs and my intake is a dual plane with 4 hole plenum openings for each carb. Would using a gasket with the open design like for a single plane intake vs a 4 hole gasket make any difference in the velocity or the vacuum draw on the air bleeds etc. here’s a pic of the carb base.

CA332V is the part number although I think 2” is about right.

those look normal are you using the factory height element? Anywho I think those are resistance welded in place.

Not sure on the tanks but the 3/8 sending unit was installed on the cars with 440hp and 426 hemi and 5/16 on the rest.

The port would come out on the bottom side of the carb and has a notch of sorts around the Venturi that would allow the nipple to see engine vacuum.
