Spectre’s universal carburetor adapter converts between 2‑barrel and 4‑barrel manifold bolt patterns (2V to 4V) for quick adaptation, but it does not fit spreadbore manifolds. The adapter is 7/8 inch thick, manufactured from precision die‑cast aluminum, and includes gaskets and hardware for installation, offering a straightforward way to adapt carburetor and manifold combinations while maintaining a solid sealed interface.
