See my other post. And the hose normally fed from that hole leads to the
heater air box, not the lower shrouds. It doesn't "blow" hot
air. Besides, it's been eliminated from my stuff seeing as how it's
useless for all intents and purposes, rather pull air from under the car
than from inside the engine shroud to "cool" anything inside the
car. Thus, since it cools pretty much *nothing* I eliminated it, less
weight and clutter to mess around with. Likewise the duct in the top
shroud, blocked off.

Yep. And it's not what the carbs suck in.

I can pull in to a gas station after driving around downtown, lift the deck
lid and it's like a pizza oven "under the hood".

Ahh.... NOW you're getting it. It's why I appreciate the Powerglide in
the 60 4-door because I do NOT have to go continuously rowing through the
gearbox pumping the clutch pedal while trying to negotiate downtown traffic
to and from work etc. I've had the experience in 5 PM traffic up
Williamson Rd with watching a jogger PASS me four times along a two mile
stretch of road as I tried to get from one end to the other. *IT* also
gets hot under the deck lid in summer in slow/standing traffic... with the
idle suffering and getting rough as temps go up etc. Sometimes it gets
*really* hot around here in summer.

NOT to mention the cars running around with the rear motor mount sagged a
bit, causing the seal to come away from the shroud lip. I do not include
the cars with dried cracked shriveled seals which just don't seal any more.

Did it cook the engine? Then again, if all the shrouding was off, and the
lid was open... maybe the low pressure area behind the van would have
pulled enough air down through the engine bay to keep it cooled. Works
for motorcycles in traffic, which cool by convection and plain radiation as
much as forced-air in such instances.
