best 2bbl carb for /6 225 super six manifold.

Ordered, yep. Let's see how it all works when it gets here, Yeah, I don't have the terminology down with the /6, despite my years and years of mopar stuff, I usually just threw out the /6 for decades LOL- so I am probably saying the wrong things LOL. That manifold I got from you is going on the /6 I have.
That Carter you have will bolt right on it. I actually prefer the 318 carburetor for one that's any above stock. It's a little richer and will provide some more fuel over the super six carburetor.
