You can save yourself a lot of money if you buy new Edelbrock carbs and use a linkage kit for the newer carbs:

It won't be "factory correct" although if the factory was doing it today this might be the way they would do it. You'll spend a lot less money and it will most likely run better with the new carbs.
If I was going to build a Max Wedge looking car these days I'd go fuel injection with dual throttle bodies but I suppose I'll leave that for another thread. The MW guys tend to get red in the face if you suggest using different model number carbs yet alone mention EFI...........
