Carb to manifold question

["Langendorfer" <langendorfer@xxxx>]

Folks:

Do I need to put a "carb to manifold adapter" on if I am using a smaller '64
413 AFB on a '67 Magnum intake? I generally like to have the same size carb
bores as the holes in the intake and have never done it this way. I know
that carb to manifold adapters were often sold in the "old days",
particularly for large carbs to smaller bores (which I think could be
reversed for the "smaller to larger" scenario), but I don't know if that was
really necessary.

Any experience/input would be appreciated!

Thanks,

Keith
