A good dual plane will still make good power.

My "stock" 427 FE, (429 ci) with an original 1964 dual plane intake, original style heads, 1965 holley carburetor 3255-1, made about 30-50 more hp and torque than the roush 427R crate motor, with "state of the art" single plane intake, heads, and carb , tested on the same dyno.
