One of the most trusted carburetors of all times -the 1850! Its 600 CFM of airflow, vacuum secondaries, single fuel inlet and mechanical choke makes it amazingly universal. The 1850SA is constructed from aluminum which compared to its zinc counterpart equates to a weight savings of 40%! Being aluminum also means it will hold its shine and can be hand polished for a custom look! Don't trust your performance to just anyone, Holley is the only modular carburetor company that has been in business for over 100 years and has powered every NASCAR champion since the 60's.
