whats the difference between a supercharger carb9blow through) and a regular 750 holley classic double pumper? could you use a 750 double pumper on a turbo setup?

Blow-Through calibrated carburetors need to have solid floats so they don't crush, the throttle shafts need to be sealed, and the fuel curve/metering circuitry needs to be calibrated differently.

yep, also no chokes.speaking of Blow thru Holley's, I have to modify a 2300 series 2bbl ( brand new 350 CFM ) for blow thru turbocharging, I have arleady ordered the nitrophotyl float, and I know to remove the choke, and oring the needle and seat, but what else do I need to do? I bought a compleate holley Jet kit ( 2 of each #66-99 jets ). This is going on a '67 Ford 200 I6, that will be turbocharged. that's currently being rebuilt.

Be very careful removing the choke tower on a 2bl, you can hurt the air flow tremendously on them due to turbulence.
