Holley Carb

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.

Racing Beat Modified Holley Carburetor Only Bridgeport 13B (uses 650 cfm carb.)

We offer the extremely popular Racing Beat-modified High Performance Holley carburetor for the 1974-85 13B 4-Port Bridge-Ported engine application. This 650 cfm – Double Pumper with mechanical secondaries – carburetor is the same modified component that is included in our complete 1974-85 13B 4-Port Bridge-Port Kit. The optional air cleaner assembly, fuel line, 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.

For optimum performance, combine this Holley carburetor with a matched Racing Beat intake manifold and the Holley Float Bowl Fuel Line.
