I believe that the fuel cut-off is RPM related not speed related.
It is at 6250RPM and with 2:73 gears you will never hit that in 5th gear due to aerodynamic drag
I think top speed in these cars depends on when the horsepower being put to the ground equals the friction forces in the opposite direction.
or with new gearing like 3.73's or 4.10's you might hit the 6250 RPM shutoff
