Ford promised a Mustang GT 205-horse 302 HO to replace the 175-horse version. Late in 1984, the 1984 GT was scheduled to be upgraded to 205HP through the use of stainless steel exhaust headers and a variety of other improvements. Prototypes developed piston problems, however, and the 1984 GT remained at 175 HP until the end of the model year. So sorry to say you have the weak 175 HP version.
