MANIFOLD HOLLEY, 79-85 12A
Holley Manifold, 79-85 12A Stock port
The Racing Beat-designed intake manifold for the 1979-85 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.
All of Racing Beat’s rotary engine 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. All Racing Beat intake manifolds are hand-ported to match a specific intake port configuration for 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 intake 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 (79-80) or (81-85), and/or Holley base gasket are available separately.

HOLLEY CARBURETOR ONLY, 12A 465 CFM RACING BEAT MODIFIED
Racing Beat Holley Carburetor Only Stock port 12A 76-85 (465cfm carb) Discontinued
Sorry, this item has been discontinued by the Manufacturer
We offer the extremely popular Racing Beat-modified High Performance Holley carburetor – 465cfm body – for the 1976-85 12A Non-Ported engine application. This carburetor body is the same modified component that is included in our complete 1976-85 12A Non-Ported engine kit. The optional air cleaner assembly and manifold shown are not included, but are available with the complete kit, or as separate items.
Each carburetor is modified by Racing Beat to maximize the performance of a specific engine application. Every carburetor is disassembled, modified and reworked by a Racing Beat carburetor technician. These modifications are the results of countless hours of engine dyno testing and real-world testing. These extensive modifications are undertaken to increase the airflow to meet the demands of the rotary engine.
This carburetor requires the use of a high performance fuel pump delivering 6 psi @ 20 gph, we suggest the use of the Mallory 4070M unit.
