Hood venting
#41
Melting Slicks
My Cowl Induction Hood was open (no door flapper that opens at WOT) and I used the stock 75 air cleaner with hood seal.
I got caught in a thunderstorm a couple of years ago driving home on the freeway.
When I got home I seen a small puddle of water in the base of the air cleaner. So no more open hood cowl, now it's plugged up.
Can't see where any performance issues come in to play since that cowl flapper was only designed to open at WOT, and I don't drive WOT. Pure GM hype for the average driver.
That, and in 76 (maybe 77) the Cowl Induction was gone.

I have a ls in mine and it looks like it'd drain water right on top the intake manifold/ throttle body. Right in front of that is my air filter. I'm not gonna be driving mine if it's storming outside but if i have gotten caught in a many showers while out. It happens.

Pzark, where did you get the fender vents?
Pzark, Where did you get the vender vents. I know this is an old post but I just came across it and I love the look. I was trying to figure out some venting for the front to help with downforce.

Interesting conversation. I am about to cut the dip or void area out of an L88 hood behind the radiator, in front of the hood carb duct box. The carb is essentially sealed at the front, cowl supplies air. I was attempting on our running car to figure out the area affected by the cowl air stack up by the windshield, and no vents there, at the back of the hood, but forward to help airflow exit, but also allow header heat to vent. Let me attempt a drawing.
