MANIFOLD HOLLEY, 74-78 13B STREETPORT

The Racing Beat-designed intake manifold for the 1974-78 13B Street Port rotary 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 13B intake 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 a vacuum source for power brakes.  If needed, an engine-to-manifold gasket (1974-75) or(1976-78), and/or Holley base gasket are available separately.

    We offer the popular Racing Beat-modified High Performance Holley Intake System Kit for the 1974-1985 13B 4 Port, stock port  (non-ported) engines. Our Racing Beat -modified Holley Intake Systems, manufactured for more than 30 years, have established themselves as an ideal way to increase the horsepower of the 13B rotary engine at a very economical price. With an open header installed in conjunction with the Holley Intake System on the engine, power gains of 40 HP are typical.

    Racing Beat’s High Performance Holley Intake System Kit has proven over the years to be an extremely reliable carburetor upgrade, with very “streetable” engine smoothness and drivability characteristics. Fuel economy is comparable to the stock carburetor under similar driving conditions.

    One of most significant benefits of this complete ready-to-go kit is that is takes all the guesswork, trial-and-error, and frustration out of attempting to assembly your own intake kit! We’ve taken over 40 years of our rotary engine experience and know-how and combined it for you in this complete, ready-to-install kit. Our intake kits has been thoroughly developed and tested using our in-house engine dyno to ensure maximum performance for each specific engine application.

    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.

    Complete Kit – Ready to Install
    Each comprehensive package includes a Racing Beat cast-aluminum high-rise intake manifold with a vacuum source for power brakes, a Racing Beat-modified Holley carburetor (465 CFM), Racing Beat Power Pulse Air Filter Canister with foam filter, throttle and metering oil pump linkages, and appropriate gaskets. All emissions control fittings are eliminated. This carburetor includes a vacuum-operated choke.

    Note: Installation of this kit requires use of a high performance fuel pump delivering 6 psi @ 20 gph.
