I have a nice set of Dual Quads (Carter WCFB) that I just had rebuilt by J&J Carburetor for $530 with shipping. They have vacuum secondary's. J&J says they are 600 CFM based on the throat size since we could not ID the carbs.
I removed the 2X4 set up and went to a single 4 BRL because I thought they were causing a stalling issue that I finally corrected by adjusting the valve lash. Thanks Y-Blockers!! (see many pages of JoeD posts on this site). Anyway the truck is running great and not sure if I want to re install the 2X4 set up again even though it looks so cool and sounds awesome when the secondary's open up! Also a sweet Aluminum Edelbrock manifold goes with this set up.
Asking $600 or best reasonable offer, lowered from $900
I live in the suburbs of Philadelphia and I will ship to you for free!
