Why run dual quads?

Easily? You couldn’t till holley came out with the 3 barrel carbs sometime around 67-68 ish.
Up until that time it was 750 cfm.

Yup. And then people started to figure out that you could put two even bigger carbs on most stuff, tune it correctly and make even more power.

If I was the OP I’d use two 750 double pumpers and not look back.
