It is a Holley from the late 50's and is the 3 bolt Ford setup. But it is
also a 2 barrel. See
www.vintagespeed.com
They specialize in those carbs (generically known as Holley 94 which has
sub-models such as my 2110 and others like the 2100). They, of course,
specialize in these carbs for Ford hotrods. However, they have all the
parts and rebuild kits.
And I agree, putting the Judson on the 164 ci is a waste of time and money.
