I am going to drive a 1973 240Z tomorrow and I'm researching what to look for. After spending way too many hours reading threads on this site and others over the past month or so I think I understand what dictates the value of these cars but I am stuck on how to identify a flat top carb. I assume that flat top carbs are flat on the top but all of the photos I have been able to find have rounded tops. How flat is a flat top? Anyone have photos?

Here's an example from the "Classified" ads on this site. Easy to see where the nickname comes from.

That's what I was looking for.
