I was being facetious about the 750 carburetor. It's WAAAAY too much for any 350 engine except an all-out racer running above 6,000 RPM most of the time. A 600 is more than enough for street use, and most high-performance applications. A 350 at 6,000 RPM only flows 607 CFM, and that's at 100% volumetric efficiency, something no street engine can do. At a more realistic 90% VE, it's only 547 CFM @ 6,000.
