    I&#39;ve always wondered how the "reverse" cowl hoods manage to get air into the engine bay.

    There is a high pressure zone at the base of the windshield when driving. They showed it in a wind tunnel once. It&#39;s hard to believe but it&#39;s there. You can put a hose from a boost gauge there and see the need move positive while you drive.

    The cowl hoods actually do a better job of pressurizing the intake than most designs with forward facing scoops.

    I&#39;ll probably use this air dam with a smoothed and painted bumper pad.

    I really like the functional/flapper cowl hood. That just screams "old school Chevy muscle." I put a Goodmark 442 style R/A hood on our &#39;91 Silverado a few years back. It fit nicely, for the most part, but definitely required some finish work before it was ready for paint. If you don&#39;t mind the extra work, that&#39;d be my choice.

    I like this one:
