The manifold shown in those pictures had a removable top, though, but I imagine the results would be similar. Those manifolds were designed to fit under the hood of the race car per NASCAR requirements of the day. They may be optimized for that application, but there are certainly better manifolds available.

This is a hi riser intake and in this case it's rarity is because it didn't work. If it had there would be MANY more of them out there as every Nascar racer would have been wanting one. The plenum area was too large and there were fuel distribution issues that Ford engineers weren't able to resolve"in the day". "Modern" thinking could ( with enough welding) be able to resolve that but I doubt it would ever match a modern single plane "spider" intake. In late '64 the Medium riser was being developed for the '65 season and little else was done for the high riser.
