Air gap underhood

I have a 69 Barracuda with a modified 340 and an Air Gap. The clearance was OK, but closer than I cared for. So I went with an Edelbrock Chrome Air Filter (any round one with a base and a lid would work) with a K & N Air Filter that was only 2.5 inches tall. That gave me the clearance I needed. The K & N people said that their 2.5 inch filter would outflow a 3" paper one, and based on the tire melting performance I have had, I agree. I do not remember the part number, but call K & N. They were very helpful.
