Holley's new 0-3310SA is constructed from aluminum which compared to its zinc counterpart equates to a weight savings of 40%! Holley's aluminum 0-3310SA will hold its shine and also can be hand polished for a custom look! It's based on the 0-3310C - a hot rod staple for over four decades! Dual feed fuel inlets assure you get all the fuel you need while its vacuum secondaries and manual choke make it amazingly universal. The famed 0-3310 is one of ten inaugural inductees into the Hot Rod Magazine Speed Parts Hall of Fame! Its well-known performance calibration and 750 CFM airflow keep it on top still today. 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.
