This adapter is used to install Holley and Autolite 2V carbs onto the US log intake manifolds. Offered in two sizes, the small 1.5" hole (red), and the large 1.75" hole (blue). The small hole adaptor is available in cast (pictured above) or red anodized billet aluminum. The large hole adaptor is available in blue anodized billet aluminum only. 

These adaptors offer improved hood clearance due to the slim design, and orientate the carb paralell to the crackshaft for the best fuel distribution possible with an adaptor. The cast adaptor comes with hardware and a gasket, while the billet adaptors come with two stainless steel Allen socket screws, four carb studs, and four nuts (gaskets not included).

We are also developing a phenoilc spacer, which will work with our billet adaptors. Not only will they serve as a insulator to prevent heat soak, they also improve airflow for more horsepower.  Therefore, if you buy (or have purchased) one of our billet adaptors, make sure to check back in a few weeks.  

Please read our tech article Selecting the Right Carb before buying a carburetor or an adaptor.
