Kristen,
The first picture is of the 260 engine that was in CSX2000, the first Cobra made. The turkey pans came into being with the big blocks if I am not mistaken. The webbers were the race set up for the 289s. The dual carbs came into the Cobras with 428 motors first as the first 60 CSX3XXX series were single four barrel Carbs and were competition cars. Then after the 428 engines they put the 427s like came in the 64 Galaxies in some and they had dual carbs. Even all of the first originals weren't the same as they used different gauges and grill layouts in some of them. A lot depended on what they could get at the time.
By the way, when you figure out how the engine works, please explain it to me. By the time Mike gets his, they won't have engines as we know them now, so he doesn't have to understand them.
