Air-Gap intake, 392 Superformance and clearance

[carguyohio]

I have seen posts about clearance issues using an RPM Air-Gap. I have the FMS 392 (430HP version from 2004). That came with a FMS intake, which is no more than a Vic Jr that was re-branded. After reading posts and looking at height size of the Vic Jr and RPM Air-Gap I pulled the trigger. My big reason for pulling the trigger and feeling confident is the height on the front side of the carb pad is actually lower than the Vic Jr, while the rear is slightly higher. However the way the engine sits in the car the smallest clearance measurement was the front of the air cleaner, meaning the lower height on the front of the carb pad would actually increase clearance.

I have yet to get it installed but have both intakes on my bench now and feel it will be fine. It is hard to say 100% as the Air-Gap sits lower in the valley, which means sitting on my bench it is actually higher, but when I deduct the part that will hang in the valley it appears to be fine. I will have it together by the 1st.

Before clearance scoop shot, air cleaner and current pics. I wish I would have taken a better scoop before pic, you cannot see it very good without back light in the bay. You can see some chrome, but the top of the cleaner is just slightly higher than what you see, IE not much room. What you see is the vertical part of the top of the air cleaner. You really do not see the angled part and top in that scoop pic.
