I only have 2" above my carb at the most and know it is not a good situation but none the less am considering building an air pan to gather 99% of the air from the windshield base in the back of the hood. It is just a regular hot air grabber as of now, in fact the hood even has restricted openings in it now. Would any of you have experiance to draw on as to what it might be worth in performance, et or hp. Car is a new combination and far from optimized with only 15 passes down to the 5.7's so far but will get to the 5.6's in another trip or two to the track. weighs 3015 lbs and 1100 hp on the dyno. There is lots of things to be worked on but this is rising on my list and I would just like quantifiable feedback so as to give it a spot on the priority list. What do you know ???
