This can hardly be compared to newly manufactured reproduction parts.
I have never understood why people destroy these carburetors as there are many who are looking for an original "regular" Quadrajet. And if you now KNOW that the carburetor does not correspond to the newly stamped number why would you even want it? There is more than a stamped number that separates a standard Qjet from a RamAir Qjet so why even bother cheating the number?

And what you wrote is 100% the problem for me. I do not know what separates the carbs from each other. I would think a 7040273 is a bigger cfm than a 7040263 and I'm sure there is more.

I don't even understand the difference between manual and automatic pontiac carbs besides the part #s.

I've always had bowties and holleys, demons, quickfuels etc. This is my first time ever with the quadrajet carbs.

I am just trying to get my ram air 4 engine to look somewhat original/nostalgic without the nasty pricetag.
