440 Cross Ram
The Production Max Wedge Manifold falls off much over 6500 and no
sense to shift over 660 to 6800.
A lot of the Stock and Superstock engines would like to
run 7500+ if the induction supported it.
The issue is the interconnection area between the two
banks is way too small.
You can cheat and open it up quite a bit but you better be
one of the best Aluminum Welders in your state to hide it
in stock.
