i have the tall big runner single plane that is all ported out....Makes around 840hp currently. I don't rev it past 6500, so I was wondering if I should swap to the dual plane and try it. Maybe even mill down the divider and port it out and run an open spacer. Did that on a small block eddy air gap and it made a fantastic difference.
PS It does not fit with the air cleaner and the hood down all the way. I even milled a little off the top of that intake and there just isn't room.
Is yours ported, and did you use a phenolic spacer?
