<VV> Oil Coolers

[Bryan Blackwell]

I wrote that - it doesn't have anything to do with Jim's double folded 
fin mod.

Do you have data that says the oil is cooler without the side shields?  
The air doesn't appear to go through the cooler without them, it 
appears to hit the top and turn to the side.  If that's the case, it 
would seem that side shields would force the air through the cooler 
where it can remove more heat.  Given that these were added to the 
later engines, I would think that Chevy concluded they were a good 
idea.
