Here is the 63-4 Ford Fairlane 427. This was the air cleaner solution.
I stand corrected. Those hoses are a lot bigger then 4". 6" maybe?
Those hoses run to inner side of the dual headlight configuration. As I recall they are in the vicinity of 48" long each?
That really is answering that question to a good extent. It shows whoever did the development on that induction that they looked at lowering the restriction to the carbs.
I believe that there are filter elements inside of the housing but I just don't remember for sure that detail?
That is a Factory Ford race car that could legally be driven on the street.
I would strongly suspect that they were run mostly without the air cleaner/filter elements.
That engine was always thought to be 600hp.
Induction was not it's limitation with 2.19 intakes, dual Holley 715cfm carbs and extra tall intake runners. The exhaust ports were very restrictive. All FE exhaust ports are.
I remember many of them "blowing up" at the drag races since 7,000 rpm's was the limit of valve spring technology at the time and they were launching at 8,000-ish rpm.
The valves were also early sixties "high tech light weight design" with the valve stems hollow and filled with sodium to lighten the weight of the valves. Many of those would break and drop the head of the valve into the cylinder.
Today titanium is the material of choice for valves but the stems wear much faster then the normal chromium-steel alloys and at $150 per valve don't give any longevity.
The W30 version of the Olds 442 is VERY SIMILAR to this design. I don't have any pictures handy of those though.
Here is a link to a similar discussion with pictures.

This is similar to what you are suggesting your solution should be. It is very comprehensive and is giving me migraines trying to crash all the alternatives in? Don't overdose on it!
