So I was able to pick up a Ford Racing 392 from a friend this past weekend. Everything is as Ford had it including the tall Victor JR intake, turns out this is way too tall.

So the question, what do i loose performance wise if i go to the Performer RPM manifold? Is it even noticable for a street car? I still have the original GT40 heads on the motor. The gears are 308's so maybe the torque will come in lower in the RPM range?
