Expavr - the blower came with that Weiand 471 6x2 bolted on top. When these Italmeccanica superchargers were sold for flatheads in 1949-1950, they were rated for 4500 Cc's, or 274 cu/in. They had mounts for 2 Stromberg 97s.

The engine is a 3/8 by 3/8 296 engine, huge ports and actually had the Evans 4x2 originally on it and was intended to run nitro. It's never been fired.

A Cfm calculator says about 430 Cfm should be plenty for a 296 at 100% volumetric efficiency. That's around 3 Stromberg 97 carbs. (150 Cfm each)

I wanted to see the blower on the engine. The blower won't have that many carbs on it when I put it to use. Sure looks wild doesn't it?
