Having said that in any form ALL the air scooped up by the air duct is pushed under the car. That I think a major design flaw and with this much work it simply bothers me to leave it that way. We hear what everone guesses about this and that on the internet. I have listened to people tell me what a bastard engine the 400 is. I like to go beyond the "Ideal internet answer". I feel stongly that the air flow is a major design flaw of the car and I am going to make the changes to my car. Only then can we see that "A" it was a waste of time or "B" HOlly cow, I never knew it could hold the road like this! I EXPECT improvements even at highway speeds and I don't see any negatives (other then a big hole in my hood).
This car was highly modified to start so I have no quams about more modification. It is a very solid platform to start. I have an early pushbutton which is next which will remain pretty much stock when I get to it.
