<VV> Block Off Plates & USA visit

The blockoff plate you're referring to bolts to the fresh air hose port on
the turkey roaster by the firewall.
The hose isn't 'needed'; the hot air heater doesn't need any cooling air.
Don't forget to block off the other end of the hose, or you could lose
heated air destined for the cabin. I've blocked off my Corvairs so I can get
heat! I believe a Campbell's soup can just fits over the snout on the heater

G'day (again) to everyone,
I very much appreciated the replies on the Powerglide cover plate but I have
yet another question concerning cover plates that I am hopeful some of you
can put me on the right track with? This time its an 'aftermarket' plate.

I 'think?' I purchased this plate from Clarks Corvair Parts some time back.
The purpose of this plate as I understand it, is to block off an air hose
that from all accounts is not required. The benefit of blocking this hose
off is that apparently it improves cooling capacity to the engine.

Anyway dispite searching the web and looking over our Corvair engine, I
can't see where this plate should be installed. It's shape does not help
either. I am guessing that the long oval shaped hose is the one that many
block off to improve cooling but I wondered what the down side is of doing
