Intake help

On a j headed or factory headed combo I would be very suprised! That is a big claim that I haven't seen backed up. The Air Gap is a great intake and I have seen it make power on many Chrysler small blocks.
What are the basics of the proposed combo? Or is it the current engine in your wagon? Your wagon does 11's or 12's from memory, I remember seeing it at the first Mopar Rumble.
