The Racing Beat-designed intake manifold for the 1971-73 12A Stock and Street-ported engine is ideally suited to meet the performance requirements of the Holley carburetor. Designed by Chief Engineer/Engine Builder Jim Mederer, these cast aluminum intake manifolds have proven themselves in a variety of street and race applications.
Racing Beat manifolds for Holley applications are cast by a local foundry then delivered to our in-house production shop for final machining and surface finishing. Each manifold is hand-machined to match the specific intake port configuration of the intended engine application. Further machining is then undertaken to match the base-plate surface to the Holley carburetor base. These critical machining steps ensure a positive fitment between both the engine surface and the carburetor base. Every manifold is then surface finished using a ball-burnishing process that enhances the final appearance of the aluminum material. Once these labor intensive processes have been completed these manifolds look as good as they perform!
This manifold includes a vacuum source for power brakes. If needed, an engine-to-manifold gasket, and/or Holley base gasket are available separately.
