Holley 600cfm Street-Legal 4-bbl Carburetors

The Best Way to Maintain Power While Meeting Emission Standards

Contributing to the safety of the environment while driving your vehicle is just plain street-smart. And now Holley makes it easier with Street-Legal 4-barrel Carbs. They can be used on most domestic vehicles that were originally equipped with a 4-bbl. Holley has engineered these carburetors for bolt-on installation on stock factory manifolds to replace existing Holley, Rochester, or Carter carburetors. Installation on spread bore style manifolds, however, requires an adapter plate for proper mounting. Each of these square flange carbs has an electric choke, vacuum secondaries, single-feed side-hung float bowls, and power valve blowout protection.
