I notice Summit as a 500 CFM two barrel called a Jet for $285
in the 2007 cat.
Holley also has a 500 CFM 2 barrel for $269.

Now if we can just figure out how to lean em.
The Holley might be easy as it has a screw in adjustable float
valve.

If by "Jet" you mean QuadraJet, those carbs do not feature an "wet"
float level adjustment. If you mean Jet Performance Products,
they take Holley cores and modify them.
