Our "Carb Swap" Kit comes with a carb adaptor, a fuel pressure regulator or an electric fuel pump, universal linkage kit, and a Weber two barrel carb with a manual choke (electric or hot water choke optional). Air cleaners sold separately.
The carb adapter comes with a custom billet insert to improve air flow and horse power by concealing the mounting screws and funneling the airflow into the carb bore. Our adaptors offer improved hood clearance over other adaptors due to their slim design, and the carb is orientate parallel to the crankshaft for improved fuel distribution. The carb adaptor is available for both 1.5" and 1.75" carb bores, and comes with two stainless steel Allen socket screws for mounting (carb studs are optional). Air Cleaners sold separately. Gaskets not included, however they can be purchased at any parts store.
Note: The kit comes with a Holley fuel pressure regulator, however a high quality Weber regulator is available (see options).
Note: You can use your stock fuel pump with a fuel pressure regulator, or an electric fuel pump (see options). If you use the AirTex Electric Fuel Pump, you do not need to use a fuel pressure regulator. A stainless steel Fuel Pump Block-off Plate is optional.
Note: In most cases you'll need to replace the stock distributor with an aftermarket distributor, such as the Duraspark II or the DUI. Please see out tech articles on Ignition System Choices and Load-O-Matic Distributors for more information.
Note: Modifications to the carb linkage are required. Some guys modify their existing linkage, while others install a throttle cable. These can be purchased new from Lokar, or you can adapt a used pedal and cable from a bone yard donor car, such as a Maverick or Granada
Note: Occasionally the carb will work fine out of the box, however in most cases you'll need to rejet the carb to get the best performance. Please see our tech article on Adjustments & Tuning for more information.
NOTE: Failure to purge the gas line and/or installing a new fuel filter will void the warranty.
Note: Not sure which carb to use, our tech article may help.
In the photo below you can see how the insert slips into the adaptor after the adaptor has been mounted to the manifold using the stainless steel Allen bolts.
Please read our tech article Selecting the Right Carb before buying a carburetor or an adaptor.
