Throttle Body Confusion

I had posted a post regarding a carburetor issue I was having with my Brave "falling on it's face" after warm-up. I'm not a mechanic and yield to the experts. The term Carburetor was used to me by professionals and so looking at the unit and listening to local professionals I had it in my mind that the unit was a carburetor but I was wrong. It is a throttle body injector that looks like a carburetor. I sent it to a speed shop and spent a huge amount of money and they got a Holly Unit tried to make it work then found out from Holly that unit would not work. They did some other stuff which has helped but I found a carburetor shop in my area that has a good reputation so I will send it to them when I can. I really believed in my mind based on the looks of the unit and what I was told by other professionals that it was a carburetor but they and I were wrong... Sorry.
