There's more to it than that. The Swedes did flow tests a while ago that 
showed the flow is OUTWARD thru the side openings until rather high speeds. 
And thats a good thing 'cause no one that sells the ears tells you to drill 
and metal-screw the chrome window frames to the body. Mad Dog ran them for 
some time before he worked his way up to about 150 mph- and the whole window 
frame ripped out of the car at a Silver State event. He never did find it... 
So yes- if you get moving along smartly, they do scoop air. But at reasonable 
speeds, the rush of air from under the car outward thru the rear window 
opening will cause air to go out the scoops, not in, so any cooling gain will 
be iffy. As sealed units with hoses to a carb top, I'm not sure what will 
happen to the carb mixture. 
Your choices are small 'side scoops', large 'elephant-ears' and smooth 
'gridded covers' that include a gas flap ('73-up), all of fiberglas. All the 
vendors sell them. On street cars, all are purely decorative but if the window 
glass underneath is removed (and not all are!) the glass is 6 lbs off the 
car weight. Good luck- J DeRyke
