Honestly, I can’t think of any of my customers who run a 2 circuit 4500 carb.
Some are on 10 second street/strip cars, some are on lightweight drag cars(as quick as 7 second rails).
Well, I guess theres one carb that might be a 2 circuit.
I never asked. It’s whatever AED built for him.
I know Dom is pro-2 circuit, so that’s the direction he will likely steer you.
