what kind of air intake is everyone using?

My engine sucks atmospheric from heaven to the top of the hood then through a filter and then thru a big old hole in the hood and BAM! into the airhorn.
Yeah, that's right, my filter is on top of the hood. When I open the hood, you can stare straight down into the boosters. The carb is,of course, sealed to the underside of the hood.

Oh, did you mean intake? Oh, in that case, I have used the factory C.I.spread-bore and TQ, and a Weiand X-CELerator, and currently the AirGap. My butt-dyno couldn't really tell the difference. I really really liked the the TQ tho.
