Someone mentioned that a 1974 corvette has the "Best Air Intake"

But getting into the physics is what many can't or won't do and prefer to believe anything that the marketeers say.
Just for fun- the '73 L82 made 250 HP net. A 100 HP increase represents a 40% gain. The formula for power increase from reductions in intake air temps is 1% for every 11*F. This means that the hood would have to lower air temps by 440*F below ambient or approx. 370 below zero on an average summers day.
D*amn them GM in-jun-eers working for Duntov were good!

On the flip side for what its worth I have seen many people post that true cold air intakes did help with Detonation issues. and it has to help keep the carbs cooler..

I know this discussion is on hood design, but since intakes were brought up......
The rpm air gap dual plane intake as tested on an early small block Chevy proved to be an excellent intake posting top hp and tq numbers. This is why it's a popular choice. I'm using 1 with a big block hood, and a dropped base air cleaner. Tight, but fits. I'm not gonna debate it, but if your interested, draw your own conclusions.
