Nope, they fit the six pack intake. There's actually more room than the chevy intake.
One can use the side hung fuel bowl to replace the cathedral type when room is an issue.
They ONLY fit with the side hung bowls, if you use metering blocks instead of plates. Those carbs on the small block manifold you show, will NOT fit as configured in the photo, on a Mopar manifold.
Therefor, since they clearly fit on that aftermarket (Chevy NEVER made a tripower manifold for a small block) manifold, the spacing carb to carb must be bigger on that small block chevy manifold.
