Michael,
I am runniing a sideoiler with a set of new/original style dual 600s topped with the K&N elements in the S&H cleaners. The hood clearance is about one quarter to one half inch, and I use chrome acorn nuts for the hold downs. The hood scoop is the standard low height, not the higher type that some Cobras use. The ground clearance is also tight, but everything is well above the main crossmember below the
oil pan. It doesn't drag on anything, but of course I am always careful when pulling into and out of driveways with angle changes.
Which intake are you using? Mine is the OEM C3 because it allowed the greatest clearance. The way the engine and tranny are mounted, the air cleaners set almost perfectly level, with the engine itself tilted down slightly in the rear.
If you need photos of anything or other info, let me know. Bob
