Troy:

I have a medium riser intake (Edelbrock RPM) on my ERA427 SC. I went with the 14" K&N with a drop base as recommended by ERA. With the drop base, the chock and air bleeds hit the underside of the xstream top. I measured the hood clearance carefully and added a 1/2 inch riser between the carb and drop base. It clears. Even though I have a hood scoop, I think it would clear without the scoop. Let me know if you need more info such as part numbers.
