Convince me to not use this carburetor.

Ok, so I am wondering why some 2 barrel carbs are so pricey. Here is one that I believe would work well with a slant 6.

You get what you pay for. That might work well, depending on it's size and jetting. My slant came with a autolite 2150 from a 3.8L Ford Granada. It worked pretty good, but my FiTech works better over a wider range. BTW, I have a /6 intake manifold that will bolt to that carb. It's not pretty, but it worked and didn't leak. Now it's in a box and I have no use for it. Yours if you pay shipping. I can send pictures.
