Opinions on spreadbore carburetors

T.Q 's do work with SERIOUS research.

Serious research? Not IMO. Add Holley air bleeds to the top of the boosters. That should help a ton.
Just look at the carb. Understand the Holley and then look at the Carters. They lack air bleeds for adjustability.
Air entry into the throttle bores are not what I call ideal.

Used the remodeled A.F.B./ Edelbrick (on purpose) on milder cars.

Agreed. There very good IMO for daily drivers and mild hot rods. Some guys have gone very fast with them because there limited to there useage.

Here is a quiz, of all Holley that were OEM, what’s the best one to use for high performance/racing?
