Product details:

They're hand-assembled right here in the USA. The carbs utilize Proform's high-flow main body, with adjustable screw-in air bleeds and high performance down-leg boosters. For maximum airflow, the air horn, choke tower, and choke control have been removed. The Proform billet throttle base plate holds everything in place with a set of button torx head throttle plate screws. Power valve blowout protection and slip link mechanical secondary linkage are also included in the base plate. To get your fuel where it needs to go, the Proform Black Race Series carburetors are assembled with purple anodized billet metering blocks that feature changeable air bleeds. Choose the cfm flow rate model that best suits your application.
