You don't have to imagine it. The '96 SVT Mustang Cobra all-aluminum DOHC 4.6L V8 redline is 6800 rpms with fuel shut-off/rev limiter set at 7000 rpms. The '96 motor had a complex aluminum intake manifold with dual length runners. The longer runners handled anything up to 3200 rpms (to assist torque at lower roms), at which time 8 individual butterfly valves opened up for the shorter runners to allow maximum airflow through both sets of runners up to the 7000 rpm rev limiter. The expensive complex manifold was replaced by a simpler design (as a cost reduction) in the '99 SVT Mustang Cobra, which reduced redline to 6500 rpms.
