moon equipment sold some of the more popular original intakes like this for the Weber side draft carbs, they produce decent low and mid rpm torque because the ports are a bit restrictive where the other ports cross and pinch in the port walls but they give high port velocity's and tend to look good and be responsive when properly tuned.
they look good and for a street car with a nostalgic look they are a great choice if cost is not a big factor, but todays better EFI and dual quad tunnel ram intakes will usually produce noticeably more peak horsepower

VERTICAL STACK SYSTEMS TEND TO BE MORE EFFICIENT AND LESS RESTRICTIVE
several companies have made several very similar intakes,in both WEBBER and EFI or constant flow injection designs most were improved versions with longer,larger ports and runners that were not as restrictive
btw I had a long detailed discussion with a kinsler injection engineer , the horizontal cross flow injection is significantly flow restricted compared to the vertical stake version below
