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.

I have a device that allows leaning of the 2 bbl Holley.  It replaces
the metering body that goes between the main venturi body and the float
bowl
on a 2 bbl carb.  I'm not sure exactly how it works though.  Best I can
recall, it has an electronic control with a knob that you turn.  I'll look
at it tonight and take some pics.

Paul,
the holley version may no longer be available, but here is the aftermarket
version of the same thing.
