The true tripower carbs used on the GTO's and 442 Olds in the 1966 period have a bigger diameter neck on them than the standard 2gc carbs. We tried the scoops I have on my 23 on my Sons 442 setup, and they are too small to fit over them. If you ever pop these, let us know.

BTW, I wish someone would repop the Cal Custom 4 barrel scoops that some call frog mouth. They were very cool and when you find them they are either pitted or if good they fetch big money. I'd love a set for the 2 x 4 setup on my 27.
