If an air filter could be fit into the draft tube, a PCV valve could be mounted to the rocker cover (preferably over the oil transfer fitting to minimize exposure to splashing.) I think that many engines in the 1970's had PCVs in the rocker cover.
This would allow for a shorter PCV tube run and a less intrusive installation - it might look more original.
Any thoughts on pulling the air through the engine "backwards"?
Just wondering aloud.
