I will vote for
no detectable difference.
I was running three carbs on flathead Fords -long ago -found out that a simple bonnet on each Stromberg 48 carb was as good as any setup.
when I switched to modified Chev V8's -Iused same setups and blew of the popular"dual four barrel setups .
The reason was that I had NO flat spot on my setup
It pulled hard from 3000 to 8000 (283 cu in) my Ford was 274 cu so I thoght the flow was enough and it was.
Actual experience on carbs beats theory all to hell .
Why?
too many variables
even the Carter /Holley/Rochester guys had more mods to dump tubes andpower valves etc., than Carter has pills.
model airplane engines are super simple setups after wadingthru this other stuff.
Especially as they are essentially ONE speed devices- no real load except full power.
Totally different as compared to engines drivingbikes karts boats etc..
Anyway the OS just needed a constant fuel head -and it ran like a champ - an anemic champ but a champ.
