Moroso 4500 Dominator to 4150/4160 Carburetor Adapter - 2in - Cast Aluminum

This cast aluminum adapter plate from Moroso is 2 inches tall and lets you bolt a smaller 4150 or 4160 style carburetor onto an intake manifold designed for a larger 4500 Dominator carburetor. It's a common solution when you've got a Dominator intake but want to run a more street-friendly 4150 or 4160 carb, or if you're upgrading from a smaller carb to a Dominator intake without changing the intake itself.

The adapter is made from cast aluminum, which is lightweight and durable enough for this application. The 2-inch height adds a bit of plenum volume and can help tune airflow characteristics. It's a straightforward part that makes a specific engine build possible without needing to swap out major components like the intake manifold.
