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. Each finished carburetor is bench checked by chief engineer/engine builder Jim Mederer.

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. See the "Holley Components" section for related intake supplies.
