Thinking outside the box
My grasp of fluid dynamics isn't what it used to be (not that it was ever that solid (no pun intended)), but I'd think that a tall, narrow intake port would keep the velocity on the high side while still achieving an impressive total flow number. If this system (heads, intake & exhaust) could be done for a minimal cost increase above the old design castings, the landscape could change quite a bit. It would certainly beat the crap out of the Edelbrock package.
