So I had the idea to divide things up to get better venturi velocity at low RPM. I have a friend who is a hardcore engine builder and has a dyno. We tried a bunch of different schemes to get the fuel distribution right, and then had to do a bunch of carburetor customization to get the carbs to deal with the uneven firing in each plenum.
Tested on a bone stock Goodwrench 350, an 11:1 compression engine with ported L98 heads and a .570 lift roller cam, and the history-unknown-but-appears-to-be-stock-except-for-headers 350 in my 1971 El Camino. The torque graph is off the Goodwrench engine.
