A lot of blow through boosted setups in the carbureted days used pressure boxes, where the whole carb was incased in a box so that the carb was operating under a higher relative pressure. By doing it this way pressure differentials from the floats to seals, etc., are the same as they would be at normal atmospheric pressure with a raised relative baseline. It's how all the Paxton superchargers in Shelbys and Avantis were set up. I don't think any of the factory carbureted turbo setups (Saab, Buick, Trans Am, Corvair, Porsche) were blow through, I think they were all draw through which is simpler to setup and get to run, but has the disadvantage of lag and surge which all those early setups had in spades. Stomp on the pedal..one Mississippi, two Mississippi, holy crap!
