Dual-quad (2x4-bbl.) intake manifolds came stock on large-port 409 heads (they also fit Edelbrock heads). Offenhauser makes dual-quad intakes for small-port 348 and 409 Chevy engine heads.

The swap began by unpacking this complete FiTech 2x4 GoEFI kit with the black finish to maintain the engine compartment theme. This was matched with a polished Edelbrock 2x4 low-rise intake manifold.
