FYI- heat does not 'escape' from the engine compartment in a cowl induction hood setup. The word 'induction' alone should make that clear.

In a cowl induction setup, the high pressure area at the base of the windshield is used to draw cool air into the carburetor. (using the 69 Camaro Z28 as an example) This is why the cowl induction hoods are sealed to a plate that surrounds the carb.

Glad to see I am not the only one who would rather build a CAI than pay good money for one. I'm really cheap I used mostly stock parts.

 

Thanks Mongo, well said!
