dual quad small blocks?

Found this on E-bay, Not sure how it would run... but would be fun! the first one is a OFFENHAUSER LA DUAL PORT INTAKE. The second is a Offenhauser dual 4 barrel Intake manifold 273-360 It has three bolt patterns on top for small carter WCFB, Large WCFB, and the standard HolleyCarter AFB pattern
