Something I read on this site reminded me of the weirdest log head modification I ever saw. About 15 years ago I saw a log head six in a Falcon at a car show and the guy had tapped/threaded the casting holes (that are normally plugged) at each end of the log, bolted on a threaded cap over the center carb hole, and used cast iron water pipe (with threaded elbows and all) to connect these three openings to a homemade plenum box that sat alongside the log head. On this box he had a Holley 4 bbl. I asked him how it ran and he said it bogged a bit at low speeds but ran great at high RPMS. He claimed he was getting a "ram charging" effect with the long "runners" but I doubted it with the 90 - 120 turns the intake charge was taking at the ends of the log head.
Anyone ever try anything like this?
