Engine combo and carbs cfm

[3W Hank]

Say I has ca 280 cu in.
Ex, 3.875" stroke ( +1/8" ) and 3.437" bore ( +1/4 )
The cam is Potvin eliminator 425.
Good ignition, or say decent ( Kurten or Kong )
Decent compression or heads or what one like to call it on a FH..
Very light valvetrain.
Modern ring tech.
Not a street rod.
Urgent on RPM.
Limited use.
Light crank, light flywheel/presuare plate.
Light car.
Say intake is a low mount race x4 direct port with tubes between 'risers'.
I has 2 LZ carbs and 2 Stromberg 97.
I can get either 2 extra LZ or 2 extra 97.
What cfm do they get ?

Will that thing even on best tuning not run good as over carburated.
( say 150 ? x 4 = 600 cfm )
I heard the LZ can has venturis from the 97 so they flow the same.

LZ venturi is 1.0625”.
97 Venturi is .97”.
94 Venturi is .94”
Choose your poison.

Alan, So can I install a 97 venturi in a LZ and they become equal.
How much flow a 97.
X4, to much for 280 cu in ?

I doubt that would offer any advantage, even if it were possible.
Beyond that revelation is above my pay grade.
