The 409 had three different HP ratings with different 4-barrel carbs.

(1) base engine had a single Rochester 4-GC
(2) middle engine has a single Carter AFB
(3) high-output engine had two Carter AFB's

Quote Jerry (Hot Rod Lincoln) "Edelbrock carbs are poor-quality imitations of the Carter AFB".

Jerry is being too kind to the e-clone; they really aren't good enough to be called a poor-quality imitation. I would rather try to make a double log manifold and eight Rochester B's work than the clone! The clones are permanently banned from our shop.

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
