No FIA cars had cut-outs in the fenders for exhaust - the exhaust ran under the car.

I would agree that a number of manufacturers over the years have slapped a small 289 nose opening on their 427 body style and called it a "289 FIA".

Have to respectfully disagree with my friend *13* - I believe that the car shown in the first post IS an NAF 289.
