The 5L Miami Ford motor is the same in the Falcon as the Mustang. The difference is that Ford Australia hand build a lot of the components (including the super charger) on the imported block and tweak extra KWs. The figures they quote are 335 KW for the XR8 and 351KW for the GT. These are MINIMUM figures and under the right conditions one will be able to get 400KW plus.
