GEARHEAD, I just finished making a direct port injection system with an air door on an adapter over a 4 bbl Clifford manifold and they will fit if you don't lay them down more than about 15 deg. The difference in performance between this and 45 deg bungs is, according to the xperts, indistinguishable. I considered a dual quad manifold with dual air doors to free up the center runner but too complicated and, after all, this is a street machine not an all out racer. I will publish when we get the bloody thing running. Kirby is doing most of the brain work and he knows what he is doing.
