Turbo or low profile Pro-charger for '65 dart slant 6?

Jeffery356, I stole that pic from TorqStorms website and FaceBook page.
It looks like a Demon 4BBL Blow thru carb. There's a difference between "boost referenced" and "blow thru" carburetor applications. You will need the "blow thru" carb and a "boost referenced " fuel pressure regulator.
Let's say you're running 8PSI of boost with 7PSI of fuel pressure. If you don't have a boost referenced regulator, your carb will only have 1PSI of fuel pressure. The boost referenced regulator will compensate for the pressurized hat.
I'd recommend asking LilNoah what he's using for a fuel system and timing. Also as stated WhitePunkOnNitro for further info, as he is experienced with boosted /6.
