  • Fuel System: Carb question?

    Right now I'm using an older AFB on my 63 non-R 289 powered Hawk.I want to change to an Edelbrock but I'm not sure what size ? My engine has been bored 040 over & balanced, I use a Mallory Unilite distributor & I also use a electric vane style fuel pump with a pressure regulator.The carb sits on a Offenhauser intake manifold with an adapter plate.The old AFB works OK but the choke acts up & if the car sits for more than a day the gas in the carb disappears & its a bear to start...Be nice now.....Thanks ahead

    The vehicle not starting is due mostly to todays fuel makeup not so much the carburator that is on the car currently. The fuel simply evaporates. A new Edelbrock will exhibit the same problem after sitting a few days . A 500cfm Edelbrock is the best choice for the 289 engine. The electric pump you have should help bring fuel into the carb before startup.

      By all means, buy an Edelbrock 1405.

      Then, put the older AFB in the Edelbrock box. I'll put in a FedEx call tag and get it out of your way, no charge.

        Edelbrock 1403 (electric choke) or 1404 (manual choke).

        Make sure you have no ledges or sharp edges when going from the adapter to the manifold. Mine took some cleanup work to get rid of the ledges (or manifold that sticks out past the spacer).
