Hopefully Ford won't do what they did with the SVO Mustangs back in the '80s. That turbo 4 would eat up the GTs so Ford had the price higher than the V8 GTs. Between the high price and the fact that it was a 4 cyl, they were slow sellers.
These days v6s are not as much as in disdain as a four cyl was in the '80s, so maybe if Ford prices them at v6 competitive pricing, this will be a good competitor to the v6 Camero. Rumors are the v8 GT will be in the 400HP range with the new 5.0L.
