Once you drive the webers and understand the throttle response you'll never
go back. That said, If you like to tinker go for it. It gives the effect
of fuel injection. I know they can be a bear to dial in but man when you get
there it is so sweet.
Like any mutli carb set up, I see, 70% of people over carbureting. This is
a case where less is more. Its in the math. Know the CFMs your engine
needs and life is simple.
I had built a SB chevy started 237 cid block, 30 over, made it 331 cid
I forget the cam now, think it was 390 lift 410 duration. Well, the power
range was was 4G -6G red line 7G street engine.
I wanted two 4 barrels on a cross ram manifold. my CFMs need to be at 780.
Yeah a single 4 barrel would do it but.............. i found a holley 4
barrel carb for a BMW rated at 390 CFM. Got two, and the best part is it had
tiny primaries and with the T-10 4 speed it got 16 MPH driving (normal).
The secondaries were monsters so full throttle was a blast. With the look I
wanted. ahhhhh the good old days. When carburetors separated the men from
the boys.

Although the Webers look cool I'd bet the right 4 barrel would make as
much power and kept the driveability.
