Wondering if anybody had tried using a 60's Ford heated carb spacer with an unheated carb manifold and Vortec heads. My cars and trucks tend to get driven year-round and I have had carb ice issues. I see they have them for square flange carbs, wondering if they made a spread bore version that would work with a q-jet. I know there are some aftermarket heated manifolds, but I would rather use what I have. And I have a deal with a local old-school junkyard where I get free stuff because I have donated so much to their cause over the years. Thanks in advance.
