Carb recommendation needed

[DartSportDude]

I'm thinking about replacing the existing Carter Thermoquad carburetor on my '73 340. Does anyone have a recommendation for a new (modern) carb that would work well on this engine? The engine is entirely stock. Thanks in advance for your help.

I have an Edlebrock 600 on my .40 over 360. Runs well.

stock as in stock cast iron intake?

only a spreadbore carb will bolt on directly....spreadbore is a thermoquad, quadaflush, and certain spreadbore model by holley...

carter 1406 is a standard bore...will need adapter to bolt on....or new intake manifold...

holley 3310 is a standard bore...also...

i love thermoquads...but...new parts???? a few are available...

i have a carter 1406 on my 73 340 duster...but i am using an eddy air gap intake...

I have a GM Qjet from Summit on a mild 318 also have a Holley 570 Avenger on another mild 318 both are very good and a big improvement over Carter/Edelbrock types especially in MPG.
