I also have a 68 SS 396. After I put on an Edelbrock Performer RPM with Holley 3310 and drop-down style air cleaner, I couldn't close the hood without using a 2" air filter. Unfortunately, the 2" filter doesn't do crap because the top part of the air cleaner hits the float bowl vent tubes so it doesn't seal. I thought about cutting the tubes down, but that would only leave about a half-inch of clearance between the top and bottom half of the air cleaner which will restrict air flow into the carb. Just my experience, good luck.
