The old Carter carbs would still need the floats replaced with non crushing type IE plastic.
Problem w/running an old carb is that the throttle shafts will probably be worn & will leak under boost pressure & make a mess.
When I was blowing through carbs, I choose the Weber DCOE side draft,ballbearing throttle shafts (don't wear out) plus the shafts are sealed.
I still needed to buy plastic floats,the brass ones crushed under boost.
You can choose what ever carb you like ,but I think the Holley & Holly look a likes are proven & literture can be had for blow through set-ups.
There are books out there on how to modify carbs for blow through applications.
Or you just install a complete incloser/Carb bonnet, then you do not need to worry about throttle shaft leaks,vents leaking,etc.
I have not seen a carb bonnet on an inline Chevy six,so not sure if it will fit. I would think the carb might have to installed sideways?
Look at Amazon books,for turbo books & carb mods.
