For "PERIOD multi-carb" from the 50's Zenith was number 1 but hard to find these days. Stromberg BXOV's were the second choice. There was no third choice, my opinion. Strombergs are out there they pop up on e-bay quite often. But they are also selling for more money that they used to just a few years ago. There are other intake systems that would put out more HP but they are not "period perfect".
Nothing says 50's performance more than Stromberg or Zenith.
