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.

...including idling in stop and go traffic in downtown?   Not everybody 
spends all their time on the highways.

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".

>recirculate!


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.

>that didn't as well...


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.
