Looks great and I absolutely love the cowl hood with the actual flapper in it!

Since I have a 72 Chevelle SS 454 with cowl induction, how is suppose to work?
The same way my '70 El Camino SS worked. There is/should be a base that fits on the carb that has a foam seal that contacts the bottom of the hood. That allows for a true CAI when the flap opens. Hears a pic of one for a Camaro.

The guy built a very nice custom truck, a ton of time spent I'm sure, I say well done. Okay sure he could have worked on some ducting to allow the pretty much worthless cowl induction Chevrolet added to the '70-'72 Chevelle running it into the airbox. Too bad this post went south.

I just never understood what the engineers were trying to accomplish, opening a vent a top the rear part of the hood where the slip stream is causing a vortex sucking out air. Well without seeing the wind tunnel results of such a door, I suppose it could cause a back flow at the angle change at the rear edge of the hood and the windscreen (windshield).

I'll keep the Ram Air setup on my '71 442 W-30.
