The Racing Beat-Modified Holley Race Intake System for the 1974-85 13B 4-Port Bridge Port Engine is an inexpensive and reliable way to obtain extraordinary power from your 13B 4-Port Bridge Port Engine. These kits are especially effective in drag racing and oval track racing.
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 system is a performance-proven Holley 650-CFM Double-Pumper 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.
These kits include the same basic components as our stock and street-ported Holley kits, but they are designed only for racing in bridge-ported, open exhaust applications. The intake manifolds have been ported to match the carburetor. The carburetors utilized are Racing Beat-Modified 650 CFM Holley "Double-Pumpers" equipped with mechanical secondaries and the choke plate removed. All gaskets, linkage, and hardware, plus an air filter assembly, are included. (Shown with optional Holley Float Bowl Fuel Line.)
The manifold may require porting to match the side-housing port shape you use. The intake manifolds and carburetors are available separately.
Note: The bridge ported intake manifold has no vacuum source for power brakes. Installation of this kit requires use of a high performance fuel pump delivering 6 psi @ 20 gph.
The carburetors and manifolds used in these Holley kits are also available separately in the "Holley Components" section. Also see the "Intake" and "Holley Components" sections for other related intake components.
