"Wasn't knocking the rpm at all. I was only trying to defend the Weiand. Heck the stock 318 2bbl intakes were single plane.There was a intake test in one of the magazines years ago, small block in a Duster. The Weiand was one of the intakes used in it."

The old design small plenum single plane manifolds actually do work very well. For decades the Torker was the gold standard for big and small mopars. Its when you put a Victor or Team G on a mild engine that the performance really suffers. The performer RPM is solid too- and is what I would run on a daily driver.
