Many times an Offenhauser dual quad manifold is used to make a blower intake- and thats not just mopars. Ive seen Oldsmobiles with the converted Offy. Now even if you get an Offenhogger 2x4 manifold your still looking at $$$$$$$ to get it converted. In the 80s the B&M pamphlet had that blower kit (small chevy) that would bolt to a single 4bbl intake.
