Now it looks like were starting to narrow the performance parameters down a bit and still keep the overall concept simple and not complicate it. Anyone else care to chime in with Mr. Braswells comments ? Some excellent carb builders do not offer the ultra large capacity carburetors. Could we have two separate competitions based on carburetor size ? SZ

You'ld basicly turn the small carb class into a restricted carb class. That's great for guys that work on 2bbl and 390 carb classes, but not for everyone else.
If you're going to run two size classes of carbs on the same engine, you need to at least make a cam change to lower the RPM and CFM requirements. I'd also change the manifold too.
