Well,Veritech,it's gonna be a round hole approximately 10 inches in diameter.
I have a holley 650 carb with a Weiand Team "G" intake.
It may stick out about 1 inch or so.
I'm gonna leave it like this for a bit,but will eventually want to put a scoop over it. I was gonna get a f/g hood from that clown at "showcars",but after reading all the horror stories,I figure I might want to avoid him and a possible assault charge(lol).
Gonna take the car to the track this weekend to see what it does.
Should be fun,but right now I can cloce the hood with the air filter on it.
Not sure if I want to chance it by running without,and getting something in the intake.
