Machined from 3/4" 6061-T6 aluminum, these billet adaptors are used to convert your stock 1V log manifold to a 2V manifold, allowing you to install any Autolite or Holley 2V carb. The adaptor works on all log style cylinder heads, however the log manifold must be modified prior to installation, which requires the removal of your cylinder head for machining.

Includes four stainless steel Allen head cap screws for mounting, as well as instructions (Carb Studs and Phenolic Spacer optional).

Please see our tech article for more information on Converting a Log Head and Selecting the Right Carb, before buying a carb and/or carb adaptor. The photos below show a converted intake using our Autolite/Holley adaptor. We also offer Weber conversion plates (see adaptors).

In this photo you can see the low spots in the manifold, which were filled in with putty prior to machining.

This photo shows the adaptor mounted to the manfold.

After the carb is mounted, a throttle cable is installed.
