Inliners International Forums General Discussion Engines Low CFM 4 barrel carb options?

I am running the front half of a Q-jet on my 1bbl intergrated head. I have the carb turned the same way that it would sit on that Pontiac manifold. Although it’s a little short on CFM the drivability is very good! I would like to try a WCFB on a little more aggressive engine. Apparently they were made in different throttle blade and Venturi sizes. Looking at the GM heritage center, some are shown with SMALLER secondary Venturis than the primary side. Jay
