The Racing Beat-designed intake manifold (1-11/16" throttle bore diameter), for the 1974-78 13B Bridge Port 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.

All of Racing Beat's manifolds for Holley carburetor applications are sand-cast by a local foundry and delivered to our in-house production shop for all machining and surface finishing processes. manifolds are then hand-ported to match a specific intake port configuration for an 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 does not include a vacuum source for power brakes. This manifold includes a vacuum source for power brakes. If needed, an engine-to-manifold gasket (74-75) or (76-78), and/or Holley base gasket are available separately.

Installation Note:
Requires four (4) 5/16"-18 x 1.5"L fully threaded hex bolts and washers to mount a carburetor to the top plate.We suggest you thread the bolts from the underside of the top mounting flange forming mounting "studs" for the carburetor. Place the carburetor over the studs and secure with split washers and 5/16" hex nuts.
