It is obvious that the small block six pack parts have gotten out of hand in price. But they are extremely rare in comparison to B or RB manifolds which I believe are both still being cast by Edelbrock and are readily available.
Disagree, but only with the "B" part of your post. The 383 Sixpack hasn't been available for years. And because they were never a factory option, I think they are rarer than the small block. There is just much less demand for the 383 Sixpack.
I have a 440 Sixpack intake that I'm not using, simply because of the price of carbs.
A Sixpack center carb is more money than a 1050 dominator.
