From reading your car specs, you would need a 4300, not a 4300D which is the spread bore. The 71 4V is not a spread bore unless your intake has been changed to a later one.
Unless you need to keep it totally original, I'd suggest a Holley 670 or Quick Fuel of similar size.
Just asking the question.
