318 draw through build

Whoa!!?? I like, but im still lost.. could this be done with a roots blower like an eaton? Since theyre made to run dry, can you set it up like a blowthrough, to push air in, but still be sucking through an adapter with a carb on top similar to that turbo draw through manifold? Does anyone understand what i mean? Lol

Is fuel still present in the blades, bakerlite?
