HOLLEY CARBURETOR ONLY, 13B 4 PORT STREET PORT 600 CFM RACING BEAT MODIFIED
Racing Beat Modified Holley Carburetor Only, Street port 13B 4-Port (uses 600 cfm carb.)
Racing Beat’s Holley Intake Kit for the 1974-85* 13B 4-Port Street Port engine has proven over the years to be an extremely reliable carburetor upgrade, with very “streetable” engine smoothness and drivability characteristics. We offer the carburetor included with this kit seperately for those looking for a replacment for the orignal Racing Beat-modified unit. The carburetor we supply for the 13B 4-Port Street Port applications features a 600 CFM model utilizing a mechanical choke and mechanical secondaries. As supplied, this carburetor does not include the mounting and attachment hardware that was originally supplied with the complete kit.
The heart of each intake system is a performance-proven Holley carburetor. Depending on the requirements of each specific application, the carburetor is disassembled by Racing Beat’s carburetor technicians then reworked, retuned, and reconfigured specifically for use with a designated rotary engine application. This process is not a simple “re-jetting” project, but a complex series of steps requiring machining, drilling and reconfiguring of the main and metering bodies, adjustment of the float bowls, and complete replacement of all jets.

Many customers have spent many hundreds of dollars on wrong diagnosis/unnecessary repairs at other shops because of this hose. Due to it’s close proximity to the exhaust manifold, the hose tends to get soft and split. It goes from the back of the carb down to a tube sticking out of the back side of the intake manifold.SKU: 13-7560-N201 Manufacturer SKU: N201-13-756 -

MANIFOLD HOLLEY, 74-85 12A BRIDGEPORT
Holley Manifold, 74-85 12A Bridgeport (74-85)
The Racing Beat-designed intake manifold (1-9/16″ throttle bore diameter), for the 1971-85 12A Bridge-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 manifolds for Holley carburetor applications are sand-cast by a local foundries and delivered to our in-house production shop for all machining and surface finishing processes. Select 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. If needed, an engine-to-manifold gasket, and/or Holley base gasket are available separately.
