Buddy Bar Intake?

I can't figure out 2 things: The top for the manifold appears to be like 2 inches thick - had to be thick to accept the recesses ground into it for linkage, and #2 the sheet metal "air cleaner" box. Do you think this was an attempt at a blow through system hooked to a turbocharger???? My STR-12 came with a blower top on it and a cracked original top (repaired twice). The seller told me the manifold was on a 318 in an early 30s Plymouth hot rod with a blower on top - YOWZER!!!
