Good replies...as far as Firehawks and SS having 345 OEM hp Skyman, check this out:

The 345 hp is standard on Hawks, optional on SS's if they buy the catback system and lid.
With respect to race conditions, I use a V1 and have had Mustangs in nothing but perfect situations to race (weather, cops, traffic, etc.) without success.
Have a good one!
